Now I'm not >300kW (400hp), but I did just switch to the NGK Ruthenium HX (95125, LFER7BHX), and they have been very smooth and responsive. I was using NGK 94833 (OEM, PLFER7A8EG), and they were fine through their life too.

[@hitmancontracts]

Unitronic suggests stock plugs with a stage 1, 1+. Maybe a stage 2 with bigger turbo would be better for a colder plug. But APR suggest 1 step colder plugs for their stage 1. 😬

MAN i just changed my plugs to ths bosch double platinum and import direct coils. the rubber on the old coils glued itself to my spark plugs. Worst 7+ hours of my life. Thanks for the video!

[@commentbeast3985]

Yeah this happened to me, the tips broke off….noticed when the reservoir cracked and overheated…the car went into safe mode because of misfires. I took the plugs out and noticed the tips gone in two of the plugs plus coolant in the combustion chamber which Ig is from the head gasket failing. I’m covered under the Pzev warranty but I have to wait and see what the dealer will say this coming monday

[@DArias]

So sorry to hear that… it sucks how more common this is becoming especially since for a long time these were the recommended plug for most tuners. I’m hoping you’re covered

Did this throw a flashing check engine light?

[@MarcMillerr]

I've been running RS7 plugs I order through the Audi dealer I work at for 2 years. I really think people underestimate PROPER gapping lol I tend to stress myself out after seeing so many posts in the groups though. Just cant justify paying the crazy prices for the other kind of plugs, especially when I try to change them roughly every 10k miles. Good video bro.

[@DArias]

Thanks bro! You’re 100% right. I do feel partially it does have to do with people gapping them wrong and ruined the ground strap which causes it to snap. That’s the issue too though so many other plugs are double the price so it’s tough. For me I never had issues it’s more of a peace of mind thing

[@Max-lq9bi]

Hi. How to know if I am using RS7 spark plugs? Are RS7 plugs also NGK brand?

[@TangAppy]

I picked up a 2017 Audi S3 and the OEM NGK plugs were loose. One spark plug lost its ground electrode. Everything else seemed good. Entire service history was with the dealer and the plugs have about 15k in them. I have a JB1 hooked, other than that, my car is stock. I would recommend people check their plugs after every other oil change no matter what set up you have. I’m just going to avoid NGK plugs for now and swap them for OEM Bosch plugs.

[@DArias]

You’re absolutely correct on everything! That’s a practice I do myself every oil change and I change plugs every other change. But I always put a socket and try to snug them just in case

[@issakorean]

had the same with oem vw plugs, but my hpfp did go out so i dont know if that directly caused that to break

[@MegaHollywood1971]

Just because a vehicle's service history is available, doesn't mean that the previous owner didn't change out other items on their own.

[@wrangler0829]

Went with brisk racing silver on my mk8. Been happy so far! Added the 034 ignition coils in red as well.

[@DArias]

Nice man! Great to hear

[@johnstevens2617]

Could be an issue of improperly gapping. So many people tap the straps on the ground or a wall to close it and end up slightly ruining them. With the strain of tuning and driving hard they break

[@DArias]

This is so true. Another reason things could happen. Like I mentioned in the video too this is the most commonly used plug so more chances for things to go wrong and pop up

[@tredfxman]

@@DArias Hey are those Denso the IKH24 model? It says racing plugs on your box, so im unsure if the IKH24 iwas lookin at is the same as yours? Also if you daily the car more than race it, would you recomend the IKH22 instead, or is IKH24 running smooth on idle as well? My car is Stage 1 GTI Clubsport 380 hp/470 torque.

[@omarordonez4013]

A lot of people run stock plugs too re gapped down and they work. Always tell people to regal their stock plugs and see if not then go 1 step colder

[@DArias]

Some people do just run stock and sometimes it works for others it causes some knock. I tried the stock plugs first and regapped but kept getting some knock at wot once I swapped plugs it went away

[@davezapata1034]

Great video. Absolutely with all the issues these have caused just stay away. Many other options to go with that haven’t had any problems

[@DArias]

Exactly I personally didn’t have issues with the rs7 plugs but this was more peace of mind

[@cesarrincon5270]

I just removed mine and the metal clips on the bottom fell off of Cyl. 3 & 4.... sad

[@Noname23489]

Did your motor need rebuilding?

[@chasewollman4431]

They’ve been failing all over the pages recently. Could be user error like you mention or just a huge batch of defective plugs

[@DArias]

Could be a combination of both possibly. I had no issues with the plugs personally but I don’t want to risk it

[@MILLIONAIR6]

as you changed your spark plugs, how about the ignition coils, was that ever replaced when tuning the car ?

[@JJ-wf2fm]

So you don’t need to gap the Denso spark plugs? I just got mine and I’ve never changed spark plugs or even worked on my own car

[@DArias]

It’s a safe bet to check gap in case it’s extremely open but most times it’s unnecessary. I’ve had 3 sets already none had to be gapped and 0 misfires or knock

[@bruceaviles804]

GREAT I’m worried now. I have 5k miles right now on mine should I swap?

[@DArias]

No need to freak out for it as long as you know you installed them and gapped them properly it should be fine. However I do suggest your next plug change to use the densos. Or if you have the extra cash to dish out go ahead and purchase! The brisk plugs work well too which are also linked below in the description

[@samwh4775]

Crazy enough I have my B8.5 Audi A4 2.0T which was on stage 1 on E85 and I did use it before many times and I had no problems, I had this spark plugs for a while in my car, then I decided to try E30 and I gapped them to 0.26, and the car blew up the same night pretty much, not sure exactly what happened, if it was the ethanol or the spark plug itself, the tip of cyl 1 broke and the car now knocks pass 3k rpms

[@johnlombardo678]

What kind of coil packs do you recommend? Currently using apr packs.

[@DArias]

Most tuners recommend using oem coil packs. The Apr ones are known to sometimes have issues like slight misfires at wot or even at idle

[@odanne29]

[@boss23395]

I recently bought NGK sparks for my VW R32 MKV hopefully no problems if I gap em properly, right?

Different plugs engine and platform so I’m not familiar with any issues tbh

[@mrdan9826]

I bought rs7 spark plugs from my local Audi dealer for my eqt stage 2 gti a year ago should I be worried??

[@DArias]

I wouldn’t freak. I had 0 issues with mine. As long as they were installed and tightened properly and gapped correctly using a proper method you should be ok. I only switched for peace of mind as most tuners aren’t recommending them anymore due to the uptick in failures

[@Jonnymic89]

Diego Thanks for the video. Did you gap yourself the Denso Plugs? I see they come as 0.028mm. Or installed them as bought.

[@DArias]

Since the ground strap has the slant style there is no need for gapping. The way the plug is set up it’s good to go out of the box! So the .028 gap is essentially equivalent to the .024 gap on a standard plug

[@entrrt]

How often would you change these out if tuned?

[@issakorean]

every 10k to 15k miles

[@prod.zbygage5143]

Hey man I have a 2017 Audi s3 with 55k miles, while I was accelerating a bit hard a “system malfunction please contact service” came up. I turned off the car and ran my OBDELEVEN and my codes were “ cylinder 1 misfire” “hide cylinder”. I turned the car back on but it ran perfectly. No check engine light I’m hoping it’s just the spark plugs . Any thoughts?

[@DArias]

It could absolutely be a plug but could also be a coil or bad ground possibly bad injector. My suggestion is if it comes back swap the plug from cylinder 1 to another and go out for a drive and if the misfire moves to that cylinder than it’s the plug. If that doesn’t work then try the coil and same thing. If that doesn’t work then check your ground wire on the coil to make sure it’s good and if those dont fix it then it’s possible you may have a bad DI injector

It depends on your tuner, most will say .024 is the correct gap. Rs7 plugs recently have been known to break BUT if you installed them correctly and gapped them the proper way you should be ok

[@natureaerials]

I just added Brisk Racing ER12S plugs. I have a stage 1 APR tune and I swear after I installed the new plugs, the engine hesitates more and is not as responsive. I believe these are colder plugs but can anyone confirm if this is why? Maybe I should only use these if I am on a stage 2?

Bought some NGK 4905 R7438-8 Racing 1 step colder plugs recommended by eqt only lasted me 5k miles on eqt stage 2 mk7 golf R. Car began misfiring. So I went to stock plugs no more misfires I don’t track my car or do a lot of pulls think I’ll be fine?

[@sarcastixx74]

To be honest mate I think you'll be fine. My RS6 C7.5 came with a stage 2 QST tuning package which is "meant to" have NGK R7438-9 plugs in them and swapped out every 10k miles. I'm pretty dubious about this as like yourself I don't do track or long pulls. At over 300 quid a set I'm wondering if a decent alternative will do. I occasionally get the odd hiccup/hesitation under minimal loads but have been assured that this is "normal". Again, not sure if I buy that or not but given that the car doesn't throw an EML or store any codes it could be true. I think tuners like to cover themselves by always insisting on parts that may be considered overkill, but also makes sense as they could have lawsuits against them if they recommended anything less and someone blows their engine. Don't get me wrong, if I ever find that I definitely do need the NGK-R's I have no probs forking out the money for them as it's much cheaper than any remedial engine work that could come out on the back of it. The NGK-R's have that angled ground strap type that is recommended by NGK for turbo cars with +50% power increase so no doubt they do the job well.

Depending on your tuner they will let you know the best gap. Most tuners to my knowledge recommend around a .024 gap

PLEASE DON'T USE THE RS7 PLUGS!!! I ran the NGK for a long time, but when they went, it damn near took my car with them. I had to rebuild my engine. Thankfully, I had an extended warranty, but I still went through an absolute nightmare with the Audi dealership. My car sat for nearly 8 months do to negligence. THEN they tried to fabricate emails and say that it was my fault that it took so long. THEN tried to charge me thousands more than what was already approved. They ended up waiving everything when I brought in the District Manager and threatened to bring in lawyers. Lesson here is NEVER go to the dealership. I ended up finding a family owned European mechanic shop, and they basically restored my faith in mechanics lol. Unless you are tuned and pushing more power just stay OEM until you get there. That was bottled up inside me now wasn't it lol.

[@DArias]

That’s unfortunate to hear. So best coils you can run are stock. People on hybrid and even full frame setups at 500-600hp use stock coils. The Apr ones are trash. For plugs if you’re tuned nothing with last a while. These cars while tuned require plug changes every 10k-15k miles. The rs7 plugs have been known to break easily which is why everyone is switching. I’m currently running Denso 5750 plugs and they’re great but I’m on a hybrid setup. For you I would go Denso 5749. Not too pricey and they’re really good and reliable according to many tuners so far

Use OEM or NGK brand which will have a serial number...Do not use cheap in Audi nor run anything that will fail to fault your engine..Do not not R7 .Run R8 if you are boosted with a Stage 1 two or 3 .Coils APR ..Also go with their tune because there is better response time with stage 1 .Let's say you tune to stage 1 make sure there are things such as the coils and sparks done and Any belts it needs. IF you can buy the bigger pully from IE then get the IE intake system..If you can get a better intercooler for the audi or Ac compressor do it ..Only get good 93 octane through shell with the V-power or additive that they have already in there gas ..Also if you burn oil in your audi like after oil changes and your like yo why is my oil going down when I just die an oil change ? Get the liquid Molly for the gas tank after you top off the liquid molly oil in your engine.It helped me keep my oil range steady. Tectron you deff want on hand post oil change ..Gas out the car to get any sediment out the fuel then fill up with the techtron
