Great video! With only a couple notes to add. First, on the passenger side being the "hard side" I found it easier to remove the wire channel with the wires installed. Then reinstalling the wires into the channel on the bench. Then installing the channel and wires at the same time. Be sure to mark the wire location on the coil end, as even though they are marked, you cannot see those markings on the coil end once installed. I would then highly recommend using a high quality anti-seize compound on the threads and dielectric grease on the wire plugs, just as a good practice. I was actually very impressed you were able to fit your fancy dancey beeping torque wrench on the 5-3-1 plugs. As they are surprisingly hard to get to. You did great there.

NGK specifically states not to use anti seize. "Anti-seize can act as a lubricant, altering torque values up to 20 percent, increasing the risk of spark plug thread breakage and/or metal shell stretch. Thread breakage can sometimes involve removing the cylinder head for repair. Metal shell stretch changes the heat rating of the spark plug and can result in serious engine damage caused by pre-ignition. Do not use anti-seize or lubricant on NGK spark plugs. It is completely unnecessary and can be detrimental."

Excellent video. Thanks for doing a complete start to finish with the spark plug change out.

Glad it was helpful!

Thanks for the video very informative, im gonna attempt to give my 08 jku a tune up based on this video, hope my check engine light will go out

[@herbcordle9426]

Good video. I may have missed it but I don't recall seeing you disconnect the battery first. That's always a good rule of thumb working on electrical.

[@SEsGarage]

Not necessary for a tuneup. Alternator or starter always disconnect the battery first

@@SEsGarage Tru that yo! 🤓👍🏻

Bro I could not route the passenger side wires back to how they were ? They wouldn’t reach the coil! How’d you make it so easy? I ended up just routing them over the top.

[@BlakWiseCracker]

Lmao 🤣 👍🏻

[@BiancaGreenJeep]

If you have after market inner fender liners, you can take those off and maybe get to the passenger side plugs a little easier. I was able to do that. I turned the tires all the way to the left and could get in there after removing the inner liner. This is a great video and thanks so much for the info. Keep up the great work!!

No never seize on the plugs?

[@SEsGarage]

I personally do not like using anti seize on spark plugs. I will on marine applications but that is about it

[@CaptTurbo]

When contact between steel and aluminum is concerned, I think it's important, especially when heat and cooling cycles are so great.@@SEsGarage

[@svrgnknight]

@@CaptTurbo NGK's website specifically states not to use anti seize

[@CaptTurbo]

@@svrgnknight I've read that too but also have fought frozen plugs too many times to not use it.

[@troypurnell7479]

Is auto lite platinum and good?

[@Crystal-jr7lp]

Wow 270,000 miles

[@jennifersantangelo5662]

Jeeps do that 😊
