E3 SPARK PLUGS-DOES DIAMOND FIRE TECHNOLOGY REALLY ADD POWER? E3 VS LASER PLATINUM VS CHEAP COPPER

DO CHEAP SPARK PLUGS WORK AS WELL AS EXPENSIVE PLUGS? COPPER PLUGS VS PLATINUM PLUGS-WHICH ONE WORKS BEST? CAN YOU ADD POWER WITH PERFORMANCE SPARK PLUGS? DO PLATINUM PLUGS REALLY WORK? WHAT IS THE BEST SPARK PLUG FOR MY LS? HOW TO SWAP SPARK PLUGS! CHECK OUT THIS VIDEO WHERE I COMPARED THREE DIFFERENT TYPES OF NEW SPARK PLUGS TO A TIRED SET OF MISMATCHED PLUGS ON MY JUNKYARD TEST MOTOR. THE 5.3L L3 WAS RUN FIRST WITH MY SUPER RICHIE, JUNKYARD PLUGS, THEN WITH NEW E3 PLUGS (WITH DIAMOND FIRE TECHNOLOGY), A SET OF NGK LASER PLATIMUM PLUGS AND A SET OF CHEAP AUTOLITE COPPER PLUGS. HOW MUCH POWER DID THE EXPENSIVE PLUGS MAKE ON THE BTR-CAMMED 5.3L?

[@Mechanickirk]

My grandfather who owned and ran a service station post WWII always said the air and fuel doesn't care what's making the spark. As long as it's the right heat range, it doesn't care. Seems like he was right.

[@THEFERMANATOR]

Now throw in a set of Bosch super plugs. They are the 1 plug I have seen kill the performance of more than 1 engine. When I worked for Dodge I lost track of how many times a car would come in running rough and low on power after a tune-up, pull the plugs to find the super cheap Bosch supers in there, swap in a set of used plugs, and the engine runs like new.

[@jacksmiththeboss]

Tried those E3 plugs in my new (at the time) 08 F150. Kept getting random misfires and sluggish performance, went back to the factory recommended platinum tip plug and the truck ran fine.

[@elmerfudpucker3204]

Use iridium plugs, but don't use those multi tipped plugs. OEM ignition systems can't saturate the coils enough to warrant using them, and yes, they are prone to setting off misfire codes.

[@tomreyn3610]

I know there is electronic feedback to the computer for fire. Plugs firing to different electrodes may send slightly diff signals. Maybe telling computer to adjust parameters. The factory spent time and research to know what’s (or which is) best. Because they do not want to burden the shops, or get a bad rep.

[@JustAGuy85]

@@tomreyn3610 Yeah, which is why I was going to say there's nothing wrong with "double platinum" plugs to the poster above. That's what GM recommended in MANY engines before switching to iridium. Edit: OH, he meant multi-tipped (as he said). I agree, that multi-tip stuff is a huge gimmick. It always fires from one tip, anyways. I'm here because I bought 6x AC Delco Professional Iridium plugs for a 2000 Buick Park Ave with the 3800 Series II engine. The copper plugs in it (don't ask, I was dumber 15 years ago) when I put them into said Buick. It was my grandmother's (mine now). 2 of them started missing a month ago. Was getting misfire codes on cylinder 4 and 5. Driver side front and rear. I pulled out plug 5 (driver side front) and the "copper core" there was almost completely gone lol. Had about 38k miles on it. I know to change them at 20k, or that's the recommendation, but it had been so long, I forgot my stupid self opted for copper for "moar power." Now I have to go through the PITA of changing those plugs. The front ones are easy, of course. But, anyways, I went with the iridium. It was right around this year model (2000) that they went from recommending double platinum to iridium... so I just went iridium. I'll sell this car before these plugs go out. OH.. and they had went from a .055 gap to a .07+ gap in that 35-38k miles. Wow... But I may continue running copper plugs in my 86 F-150 5.0 EFI. Easy to change. Not sure if it would hurt anything going to iridium, though. If not, I'll just go with iridium. I have the timing bumped up and run 93 octane in it. I'll read into it it sometime.

[@zachs6879]

I've used them on a few vehicles. They are best suited for older carbureted vehicles. I did use them on a 97 thunderbird though, and it didn't even want to run at first. After I disconnected the battery a while to hard reset the ecm, it was fine and performance/mpg showed small gains.

[@katieandkevinsears7724]

I did that in a 2011 Fiesta. Immediately put the factory plugs back in and the misfire went away.

[@JBAutomotive794]

Man Richard preaching what I've been saying for years. I managed a parts store for about 10 years and always preached this info. All plugs if firing will make the same power. The difference in high dollar plugs is that the expensive alloy plugs will last longer without burning out and fouling as quickly as something like copper plugs. The NGK Lazer series plugs are designed with oem companies to be the best plug and are usually the OEM installed plugs. The only way to change how much power is Made is by changing cylinder pressure, either done by combustion chamber design or by forced or chemical induction. Copper is an ideal conductor. It's the reason your home uses copper wire. But in an engine it will burn away eventually.

I'm glad to finally see E3s on the dyno. I am a tiny bit surprised. I've always suspected they would actually KILL a little power, due to the shrouding by the numerous and massive ground electrodes.

[@The_Fat_Turtle]

They can work alright, but they do not last long. I wouldn't give more than 6-12 months on them before misfiring. They seem to work better than Bosch +4's but just about any standard plug from any manufacturer would work better.

[@misters2837]

@@The_Fat_Turtle I have no idea where the Hate for +4s comes from....I put a set in My Chevy W/T with Vortec V6 when doing the tune up at 100K....I checked them at 200K and they were still good, at 286,000 miles when the body became unsafe for road use due to rust, the +4s were still in it, Now its a Farm Truck that gets used for wood hauling, it was -15F yesterday and it fired right up...there is over 180,000 miles on those plugs and they still run like new.

[@flinch622]

The variances will be lightly affected by chamber geometry, which means the test here only covers LS heads. As an aside... I hate dealing with autozone. I have gone in with manufacturers part number in hand only to receive dumb looks [since their training stops at year/make/model], and to add insult to injury I get told to go look up their unique in-house part # on THEIR website so they can "look it up" in store. Preposterous business model if you'e a hot rodder. If there is one thing I like about E3, its that design forces a more asymmetrical flame kernel compared to traditional design. What I don't like about E3 is their website - no filter to drill down on reach, sealing design etc. Also... no downloadable catalog that I could find. I guess the NHRA guys all have to call? Aftermarket heads do not fit in the year/make/model box

[@MrTheHillfolk]

All it does is have more sharp edges than a normal plug, and plugs like to fire from a sharp edge. Tbh I've seen more runability issues because of them, so I'll swap in standard plugs and retest the problem.

[@GTStuning-]

I have a naturally aspirated LS7 that I have ran NGK TR6 spark plugs in platinum and copper variety at the same gap. I noticed the copper plug seemed to change the exhaust sound when revving up from idle, like it had more power as it swept through the revs. I didn't think much of it and installed a fresh set of platinum TR6 plugs a few months later. The sound and ease of revving from idle was reduced. This year I removed the platinum plugs and put in a set of copper TR6 plugs, hey guess what...the sound is back when revving from idle, sounds meaner. Your test definitely helped shed some light on subtle gains. On the chassis dyno though I didn't notice any gains that stood out at peak hp, maybe 0.5 to 1 hp at peak hp between the 2 materials, similar to what you showed.

I understand that copper plugs don't last as long, but haven't managed to wear out a set. -- Yeah, I've had no-start situations and check engine lights that were fixed by putting new plugs in, but for all I know, the plugs could have had some sort of defect.

Over 40 years working on cars. These are some of the problems I've run a crossed. 2 Mopars, one with a slant 6 and the other a 360 that wouldn't start with champion plugs but ran ok with autolites. 3 Fords with point distributors that wouldn't start or missed like hell because the distributor lost ground. Despite the fact the distributor has contact with the oil pump, cam and block and a new ground wire for the point plate to the distributor. A simple ground wire running to the distributor solved the problem. 3 cars with severe misses because the tech used way too much gray anti seize on the plug threads. Cleaned them and the plug holes and use a very small amount of the same anti seize and problem solved.

I work with CNG heavy duty engines that use the 3 ground electrodes with a tiny gap. The 3 prongs and tiny gap are designed to keep the ionization of molecules from being blown out. On a gasoline engine I would assume no difference unless under high boost with high swirl combustion chambers. So there is a place for fancy spark plugs but not an LS.

Maybe, and I mean Maybe when people were still using points type ignition and a 20 to 1 wound coil making less than 20,000 volts for a spark, it might have been possible to make an actual gain from a possibly better plug. Then again, there woudn't be much gap with a coil that weak. Fast Forward to these days with 40k to 60k volt coils on plug or short wire with 8 individual coils that will jump .100 gap all day long and the plug just isn't going to matter.

I got Diamondfires for my 1MZ-FE recently firing a parts gun at a developing backfire issue, they seem to work pretty well so far. Granted, when I pulled the old ones out it became clear to me that they had seen the full 316,925 miles that this engine has run in its 21 years, horridly burned up, with tons of transfer deposits on both the ground and electrode, and about a third of the ground literally burned away judging by how thick the spark point was compared to the arm leading up to it. I didn't think that the diamondfire thing would do much of anything power wise, and this video kind of shows that is the case normally, but coming from the plugs that were in there, with how out of spec they had become after running for so long, I am actually seeing some extra power out of them. As for fuel economy, I can't say anything yet as they've only been in for about a day and one short drive to make sure everything worked at least as well as before, though I didn't get to test the driving conditions that I was getting backfire through yet. I'm not saying to get diamondfires or laser platinums, just, don't be like the original owner of my '03 Avalon, do more regular maintenance than just oil changes.

copper is a much better conducter than those exotic metals. so the copper plug will actually make a hotter and bigger spark which means combustion will be just a tad better. but they will not last nearly as long as the exotic metal plugs will. a fuel economy and combustion chamber deposit comparison would have been very interesting. would have also been interesting just to see the plugs fired side by side outside of the engine.

From what I've read, indexing and plug construction is that last 0.1% you are looking to find. And sometimes that last .1% is worth the effort when you are racing. Certainly not worth all the effort on a 100% road driven sports car. Have you looked at the difference between copper resistive and copper non-resistor plugs? Maybe in combination with resistor and non-resistor wires? Wondering if the resistor changes the spark enough to see a change.

[@averyalexander2303]

From the testing i have done, non resistor spark plugs generated a stronger spark. I have a video of testing that on my channel. The problem is the interference from using Nology non resistor spark plugs messed with my ECU.

[@ChurchAutoTest]

You would expect more spark energy, but probably not a huge amount. Jumping a 1mm (0.040") gap at 10 bar (150 psi) of pressure takes about 30k volts. A typical resistor plug might have 5kohms of resistance, and if you have a plug wire (like an LS engine) that's probably another 4-5kohm or more. That means that you're generating no more than 3 amps of peak current and that's only during the initial ionization of the plug. Theoretically less resistance could result in a better initial ionization event, but the RFI as Avery says is a big deal on modern electronics.

[@averyalexander2303]

@@ChurchAutoTest How did you figure out that an ignition coil will output up to 3 amps of current? For the output current to be that high, wouldn't the input current need to be very high too? A typical output voltage of 30kV X 3 amps is 90,000 watts. At 12 volts, 90,000 watts would be 7,500 amps and there's no way a coil could draw so much on the input side.

This result totally makes sense, given that a fine mist of gasoline is VERY easy to ignite, then combine it with the heat and pressure in a combustion chamber the spark required is not very much. the only reason for the exotic metals is simply due to the fact they last much longer maintaining the engines performance which reduces emissions and maintains economy.

[@tomreyn3610]

I think any ignition hardware upgrade (coil, wires, plugs) will not bring HP, but…. Conditions of mixture, maybe a flood wash, or even a lean condition, recovering to a good burn may be the difference. Longevity IS the factor. A good test would be running under a rich condition. Which plug will light the fire?

[@MK-hb3xc]

After watching this and the Engine Masters show on plugs it is pretty clear that bigger gap to an extent, will increase power, not the specific plugs. I found that to be true when I had a Moto Guzzi. I replaced the junk weak stock coils with Ford Motorcraft coils (used) with ballast resistors. It immediately had a hotter spark and I could gap them out to .040". I won't say it ran better, but with what I've seen I would say it did probably work better. Did run and idle better at low rpm. My brother did the same change on his RD400, as did a friend with his RD350, definitely an improvement and no fouled plugs. I have to believe it is the bigger hotter spark of the wider gap. The voltage to jump the gap has to be higher and obviously the gap means a larger spark as well. I found this and Holdener's other video where he did gap changes when looking to find some factual proof if E3 did anything or not. Clearly not. Yet there are people claiming 15-20 hp gain. A bit hard to believe for sure now. I could believe they may make engines run a bit better if the gap to the electrode is bigger making a larger hotter spark, but all it takes is one spark to fire the mix. And that spark will be between the best two points to fire, not all over the place, like when there is consistent electrical pressure making the spark virtually continuously firing. That doesn't happen in the real world of firing the fuel mix in an IC engine. One good spark and bang! It fires... flame on!

[@Flexxx365]

I'm surprised you haven't done a ls coil pack dyno test. Rumor has it the round coils with heat sink at the top auto fire causing engine failure on the dyno.

[@Fljeff7]

Once again a great dyno test run video. Take a look at when exotic type plug became more common place . It seemed to be when OBDII became the standard in 1996. With this system part of it was a vehicle that would remain clean running for 100k before needing significant service to the engine. The exotic type metals would do this. Copper plugs did the job for 75 plus years before o.e. install was a exotic metal type. I welcome other thoughts and observations on this.

[@raptor50trex]

I wonder if there would be any difference if it was running with a massive shot of nitrous and/or a ton of boost

[@G0DF47H3R_]

I used to believe the platinum hype in my early 20's but was told by a racing team to just use standard copper plugs, like NGK, on my 350 sbc and I have ever since. Plats may last longer but I would still change them during a tune up anyway.

[@nickcook7408]

Silver plugs are better than copper, because lower resistance is better than high resistance. Super fine tips and tips with square edges are better than thicker tips or tips with rounded edges ( for a given material) If You’re concerned about lifespan and maintenance intervals your not concerned about your engine.

[@nickcook7408]

My favourite plug, which I’ve found to work flawlessly in EVERY SINGLE APPLICATION I’ve ever used them in was the Bosch +4 Super Silver.

[@vaderwasframed3668]

To my ears the entire and the lasers, sounded mutch smoother than any of the others.

[@richardholdener1727]

YOU ARE NOT LISTENING TO ACTUAL RUNS

[@WVXL64]

I've never believed any performance gains from plugs. Ignition is ignition. I think it's more if your ignition system can reliabily fire the plug. And I think it's less of a worry on these V8's with high powered ignition. I have a 1994 Kawasaki Ninja in the garage that no matter what I did, I could not get it to run. Last thing I did was change out the brand new Autolite plugs to a set of NGK platinum and it fired right up. I'm thinking different resistance through the plug let one fire and one not to. I think that's the biggest thing with plugs, other than life span.

[@barnes4g63]

I wouldn't expect much of a difference on an na motor but would be interesting to see if it would on a 4 cylinder under alot of boost/turbo where ignition can be a factor.

[@rhubarbpie2027]

Agreed, maybe with lots of retard/ advance would affect the outcome.

[@b.c4066]

nope, if that were the case they would be original equipment on turbo or supercharged cars. if they even improved power, economy or efficiency by a consistant 1/2 % they would be used by oem, but they are not.

[@barnes4g63]

@@b.c4066 my mitsubishi had a 2 ground strap spark plug from the factory. And you would have a much better chance of making a difference under higher pressures than on a na car. But usually just close up the gap. Again why I thought it would he a better test of those spark plugs claims. If your plug is doing the job already you aren't going to see any benefits.

[@Justls1v8parts]

The man knows he tests it for all off us before we waste cash in the wrong place.

[@BOOT]

Multi Tip plugs supposedly work better on center type chambers, like you see with Four valve or Hemi heads. Side plug type like in most V8's SBC, BBC, LS, SBF just a normal single strap

[@richardholdener1727]

EVEN ON MULTI-TIP PLUGS, THE GAP IS JUMPED TO JUST 1

[@BOOT]

@@richardholdener1727 I agree But it's not the number of tips, it's the open top area for those type chambers. Supposedly!

[@E85_STI]

I keep seeing these E3 on the tv shows like gearz but I wouldn’t ever run these in my car. I did put the E3 in my lawn mower and pressure washer. It seemed to run better.

[@rxrcond4life]

Put E-3's in my Denali Yukon, 6.0. Only used them because they were sale on Amazon for $2.99 ea. Haven't noticed any difference. Years ago, my Cheville (396, 12.2 CR, big Chet Herbet Cam (don't remember), M-22 Rock Crusher, 3800-lb clutch, ran 11:88, 141-mph in '72/73 at Irwindale. The real Irwindale where the brewery is now. AC's lasted the best followed by NKG. That motor ate plugs like a big dog eats steak!

[@jonnathwill8318]

Ford has a hybrid copper core and nickel spark plug which are two of the best metals to use and you can get them online for around 24 bucks for eight 50k mile life

[@thisisyourcaptainspeaking2259]

My favorite gimmick spark plug!

[@bbehzadi413]

My Saab tuner recommends NGK BCPR7ES-11 copper plugs they’re affordable and I change them every other oil change

[@superstockamx9064]

Try BRISK Multi Fire Spark plugs. I have had good experience with Brisk plugs and thought “no way” on the multi fires. At $15 each x 4 on my modified 2015 VW CC that operates up to 29# boost, at the 1/2 mile drags I swapped out the NGK’s for the Brisks and picked up .92 MPH. This was same heat range equivalent to the NGK plugs. I put NGK’s back in, lost similar MPH. Same results in 1/4 mile drags but around 1/2 the improvement. MPH = HP so obviously they do work. However, I believe they lead to early coil issues and are good for only about 15,000 miles on the street. So I just load them up for race nights.

[@richardholdener1727]

EXPLAIN HOW THEY MAKE M0RE POWER IF THERE IS NO MISFIRE

[@c0c0asauce]

I use what's recommended when I have an OEM ECU. Aftermarket ECU I run NGK Copper.

[@crich795]

The Austin powers laser reference had me rolling 😂

[@therealRustyShackleford]

I've ran them in all my zero turn mowers (mow commercially) and I will say the only thing I have noticed is that when in a Kawasaki engine, it does start faster. Nothing different with starting in a Briggs or a Kohler and nothing different in any of them while working the mowers.

[@Fbomber89]

I ran the E3 plugs for about 10k miles on a Pontiac 400. When I removed them I discovered the center electrode had broken on 3 or 4 of the plugs. I've never seen that occur before. I'd never purchase them again.

[@JohnBoulding]

I.woild only run E3 in two cycle engines .they have a high failure rate. I only run Densomor NGK myself and recently tried the rutheniums in my skyactive 2.5 Mazda 3. They are great plugs

[@mattangelo1280]

Project farm tested plugs and the e3s actually were more fuel efficient. Pretty wild test

[@richardholdener1727]

I love project farm-but would like to see much more data

[@EGGINFOOLS]

The E3 caused a host of misfires in my 2.2 s10. I did gain some MPG. About 1.5 to 2. But it didn't like to idle. Went back to ac delco after about 5 tanks of fuel

[@mikebrunello243]

Yeah same here the E3 spark plugs are junk

[@65sohc]

Your results are what I expected. However it is interesting that one of your colleagues, Jim McFarland, was involved in the development and testing of E3 plugs. He published a number of scientific papers on the differences in burn initiation and flame propagation compared with a conventional J-plug. There is an interesting video done at Michigan Tech demonstrating the benefits of the design. I suspect that the weaker the ignition system the more likely they would be to show a benefit but, as your test showed, today's high power ignitions will fire anything.

[@hydrocarbon82]

I recall reading about an individual coil retrofit on a 5.7 vortec (sbc) and they had pretty substantial gains in the mid range. That's likely why there was no big gain here, the LS has plenty of spark. My own experince with LS's running fine with rounded copper plugs with >0.080" gap supports that idea.

[@johnny0454]

@hydrocarbon8272 Great info, I'd like to read that if you can perhaps remember the source?

[@ElPants21]

I was under the impression copper works fine, it just doesn't last as long. So on an engine you have to pull the inake to reach plugs on or where access is otherwise poor, it's cheaer to pay up front for 100k mile plugs than sway coppers every 20k or so

[@jonnathwill8318]

Ford has made a hybrid plug using nickel and copper that expands the life of copper core plugs to 50K miles but on a side note yearly maintenance should be your priority on a car that you really love which includes changes spark plugs and other things yearly to make sure your car is running at it optimum

[@lucky7s94]

I still run the plugs my cylinder heads were designed and engineered with.

[@Adam-nv9zo]

I love these comparison videos

[@scottcyrus2659]

I like your videos short to-the-point not all the technical mumbo-jumbo but when you say it made a little bit of power you need to say how much power if it's a corner of a horsepower more than let us know cuz that's what you're comparing is not just a little bit can't measure a little bit. You said the same thing with the 8.1 changing headers it made just a little bit that was 10 horsepower and torque that's quite a bit that's info we need to know so thank you keep up the good work

[@richardholdener1727]

please look at the graphs-the plugs made zero difference

[@Matp345]

With all the positive reviews with E3's I honestly thought they would've made more. People say they gain mpg's from them but that's low rpm cruising.
