How to Replace Mazda 3 Spark Plugs in Under 5 Min!

[@UnpaidInternn]

NGK’s position on anti-seize NGK spark plugs are manufactured with a trivalent plating. The spark plugs display a silver or chrome finish on the threads. The trivalent plating reduces corrosion resistance from moisture and chemicals. The trivalent coating also acts as a release agent during spark plug removal. NGK spark plugs should be installed DRY, WITHOUT anti-seize. NGK reports that tech support personnel have received a number of calls from installers who have over-tightened spark plugs because of the use of anti-seize. Anti-seize is a lubricant and affects torque values by up to 20 percent. If you use anti-seize against NGK recommendations, you MUST decrease the set torque on your torque wrench by that amount or risk breaking the spark plug, distorting the shell, or damaging cylinder head spark plug threads.

I'm nearly 70 and I've been changing spark plugs on cars from the 60's to today. Never, have I ever, had to use a breaker bar to remove a plug. A socket, a ratchet with an extension is all I have ever needed.

[@eds6569]

I just typically use whatever works to remove it, I may have used a breaker simply because it was easiest to pull out of my junk. Just because he used a breaker bar doesn't mean he had to nor is it the wrong way if it worked. I also always went by feel on torquing it but that's just me being lazy and most repairs should be torqued to spec if ya wanna do it right and avoid potential problems.

[@BensCoffeeRants]

Using a power tool to screw your plugs in is a bad idea, FIRST do it by hand so you know it's aligned properly and won't strip the threads!

[@OliverPorter92]

Thanks for watching, this is a valid point.

[@StacksSats]

LOL

ABSOFUCKINGLUTELY!

Yeah I'm no Fu, 😜 kin mechanic but I thought that was crazy s*"t dude...f"*kin drill to insert spark plugs..😂😂😂😂😂🥰🥰😍😍😂love it..

[@slickstrings]

Ngk specifies no compound on the threads. The shiny chrome like threads contain a single use anti seize. Do not add more.

[@tenders]

This was very helpful, thank you. Didn’t have the fancy spark plug socket with the rubber gripper washer, but did have a deep socket and a ratchet extender that made it easy to unthread and rethread. Used a needlenose pliers to pluck the unscrewed plug out of the hole and get the new plug started - no drama whatsoever. No need to use power - the threads turn easily in both directions once broken free or started, and you want to manually feel the progress of anything being screwed into an expensive and fragile aluminum part like this.

[@TheWrecker93]

If you didn't have the spark plug socket you can use a short length of rubber hose to start the plugs when installing them. If you push the plug into the hose enough to grip but easy to pull off once the plug is started. Used it a few times when no socket was available.

Thanks for the video. Now I just need tools

Thanks for watching, good luck on the job.

[@denttech2515]

I would always recheck the plug gap, just to make sure. You never know what happened to them before reaching your hands

[@palewriter1856]

Whoa!!!! Rookie mistake at 2:50!!! NEVER start plugs (or anything else IMPORTANT -- ESPECIALLY into Aluminum! --- with power. Oh - I see Ben already called this! Oh well -- use the force, Luke, on SOMETHING ELSE! You really want to FEEL WITH YOUR FINGERS that the threads are starting OK!!! After that, apply power IF it's not TOO MUCH torque for the situation! Sorry Ben

[@olaznogmolotov1420]

Silly question. How do you now how much torque to use to tighten the spark plug?. Do have to use a special tool?

[@BrandonSchmit]

spark plug fall into the engine? Nope. Physically impossible. Think about it.

[@mikemonda2010]

Brandon Schmit I was cringing the whole video. I’ve been a professional auto tech for 7 years 😂😂

[@GoaWay...]

I don't get the torque pound inch thing. If the manual said do between 89-120 lb of torque, why did you set it for 10lbs?

[@OliverPorter92]

Thanks for watching. My torque wrench is in ft-lb, so divide the 120 in lb by 12 to get 10 ft-lb. Hope this helps.

[@GoaWay...]

@@OliverPorter92 thank you. 😊

Great video, thanks for sharing!

[@elenaberwick3980]

Is there a real need to disconnect electrical connectors from the coil holders when there is no electricity. Everybody does it but is it really required?

[@unittwophoto]

makes them a lot easier to pull all the way up. wiring usually isnt long enough.

[@xHaBiiiTz]

I doubt it took 5 minutes to do this.. and for one the plug can’t fall farther inside the engine and two, never use a power tool to screw in a spark plug. Just tighten it by hand to 1/4 turn past snug

[@OliverPorter92]

Thanks for watching - and yes to all of your points. It took longer, but I wanted to explain it concisely. And as Ben said in comment below, that was a poor technique that I will not be using in the future :)

[@tenders]

It takes less than five minutes per plug once you’ve got the cover off and the right tools in hand!

did any lights show up on your dash because you changed the plugs?

[@OliverPorter92]

Thanks for watching! No, there are no dash indications.

did you use BOSCH?

[@OliverPorter92]

@@gruesomely2760 Thanks for Watching! I used NGK.

[@PlaneGeekTravels]

I installed the same plugsnon my 3 , it fouled thr plugs after a day. I had to return the plugs and installed an oem plugs gapped at 0.052. Apparently, the gap matters!

[@OliverPorter92]

Interesting. Still driving one month later on mine and no sign of issues. How did you know they were fouled? Did the car just not turn on?

[@PlaneGeekTravels]

Day 1 was fine. Day 2 my car struggled to start. I removed the new plugs, NGK LTR5IX-11, then the tips were all black.

[@PlaneGeekTravels]

Then i just decided to buy the oems from mazda

[@OliverPorter92]

Interesting, happy the OEMs worked, I would have done the same if I had the same problem. Before and after replacement I have 1-2 times a week where the start struggles, but I doubt it is the plugs since it is not significantly different over time.

[@BenScarbalis]

PlaneGeek Travels can you link me the ones you bought?

[@wallmartkiller]

At 3:20 you said that those bolts on top need very very little torque. How many lbs of torque? Please

[@clarencesmith9580]

Educated elbow pounds around 5 for the metal and the plastic do-dads around 2. I have been twisting wrenches for over 45 years in my "back yard" and it's something that you learn by doing. Those 8mm bolts I would use if it fit a 8mm deep 1/4" socket and a stubby 1/4" ratchet and only tighten them just past hand-twist tight and the same for the plastic top keepers.

[@foxlake02]

The spark plug socket also works on the plastic nuts that screw onto the smaller screws too.

[@OliverPorter92]

Thanks for watching! Which nuts in the video are you referring to?

[@foxlake02]

The nuts you used a 15 mm wrench on. I used the 5/8" 6 point socket that I used on the spark plugs. Worked fine.

[@OliverPorter92]

Ah! Sorry, totally blanked. Awesome. That makes it a lot faster, single-socket job! Thanks for recommending this.

[@wgomez71]

What's the gap on these ?

[@OliverPorter92]

Thanks for watching! Manufacturer OEM gap is .052" according to other sites I read, these are .044" and most part stores claim compatibility, no problems so far with them, mileage same or better than with old plugs.

[@xKopiko]

How old were your spark plugs before you changed them?

[@OliverPorter92]

Hi, thanks for watching! I replaced them at 85,000 miles/5 years. They probably could have lasted longer; I just changed them around the recommended interval (75K-85K) since it was a relatively cheap, simple, and fast job.

[@tenders]

Mine went 140k miles and still looked pretty darn good. Just a little erosion from the electrodes compared to the new Iridium plugs. I was really surprised. (‘07 Mazda3 hatch.)

[@MarcoMedina_P]

Don't ever use a power tool on the actual engine whether it be an oil filter or spark plugs save you a headache if you just do it by hand

[@toyminator24]

It is videos like this that send vehicles to the dealer with major problems like a stripped spark plug hole. You my friend should keep your day job and not fix your own car. Never use a power tool on spark plugs!!!

That Mazda needs new motor mounts.

[@OliverPorter92]

Thanks for watching! Yup. That's going to be a big job soon. Makes the characteristic shimmy/vibration when shifting in lower gears, mounts are probably trash.

[@jchavez53]

@@OliverPorter92 Changing motor mounts on this car is a piece of cake; very easy job.

[@Jay-qb5vg]

You're not supposed to put anti seize on NGK plugs... secondly, ALWAYS! put plugs in by hand, not a freakin power drill. you can cross thread so easily doing that and making a nightmare for yourself, or anyone you have watching this video... in all honesty, you really should take down this video.

[@RichardSmith-ic1zw]

Ten feet pound of torque you gonna need 5 people to kick the shit out of that wrench 🔧

[@unittwophoto]

dont EVER install you plugs with a power tool or air tool. thread them BY HAND ONLY, and then torque. video was going well until i saw that .

[@OliverPorter92]

Yes thanks, major error in the video.

[@fearpancho6922]

Dood used a drill that triggered me like dood men if you work on cars no need for power tools for spark plugs n plus your hands is enough to tighten everything

[@spike378]

Say very careful to set it back in then proceeds to use a power tool

[@jaysonhengstberger3638]

This is a "How To" video of how to successfully change spark plugs the wrong way.. NGK and anti seize?? Breaker bar? Zip zip to install plugs????? Dont do anything from this video and read instuctions on parts before installing
