How-To: Replace Spark Plugs on a 2.0L Jeep Wrangler (with part number)

/ @odysseyusa
These are step by step instructions on swapping JL 2.0 turbo Wrangler spark plugs.
Update 6/8/2023- With the current Mopar plug shortage for the 2.0, I’ve heard the NGK part number NGK 90219, sku ILZKR7G7G Laser Iridium spark plug is the same plug (NGK is the Mopar supplier)

Im convinced that Jeep, as a corecompany value, believes that anybody doing the most basic maintenance or repairs, can go f*ck themselves 😂. Thanks for the clear and informational video!

[@NicoleHikesalot]

Awesome interesting process. Great work 👍

[@odysseyusa]

Thanks! I appreciate your watching and your feedback.

I was thinking, "did this man seriously use a torque wrench for his engine cover?" But you know what, it doesn't hurt, and I now know the torque rating.

[@odysseyusa]

Lol, yeah. I guess it’s the Air Force Crew Chief in me.

@@odysseyusa i wonder if the QA on a submarine is worse

[@odysseyusa]

I hope it’s on point! lol

SOLID - Thanks ! Curious why no never-seize.

[@odysseyusa]

It’s the plating they use on the body of the plug. NGK does not recommended it. After 66k miles, there was no issue removing mine as you saw. I prefer it that way too because you don’t have to account for the lubricity affecting the torque applied for the same setting. You wouldn’t want that. It would be too high with any lubricant on there.

What size wrench for the spark plugs though that wasn't mention, thanks!

[@odysseyusa]

It’s at the 53 second mark in the video but it’s a 5/8” spark plug socket.

[@trevorjohnston3435]

Ah I must of missed it my bad, thanks informing me! Also, sorry to ask but do you have any idea where the map sensor is, I've been looking everywhere online and can't find it anywhere in the engine bay along the air intske

[@odysseyusa]

Seems there’s a map and T map sensor. This thread has a pic showing the T map area. Maybe ask more questions there. I’ve not had an issue and looked into it. www.jlwranglerforums.com/forum/threads/blown-map-sensor-on-2-0-l.75823/

[@sergelamontagne3323]

same sparkplug for any 2 liter ? (2018-2023 ) ?

[@odysseyusa]

Always verify but to my knowledge all years of the JL 2.0 to this point take the same spark plug whether it’s in the 4xe, 2.0 eTorque, or the standard ESS (Engine Start Stop) version.

You’re welcome. Happy to help.👍🏼

Can you put a little bit of Anti seize on the threads, that sound is cringing .

[@odysseyusa]

NGK recommends against it. As a former engine machinist/builder, it’s normal for them to be a little sticky but be sure not to cross thread them. I would not use a ratchet until a few threads were properly engaged. Then torque to spec. Using anti seize lowers friction. The torque wrench works on resistance. Lowering resistance will put you higher on torque to the spark plug than spec’d. Any lubricant will. All that said, it’s up to you. If you put any on, set the torque wrench to the minimum torque spec at least.

[@odysseyusa]

Also, anti-seize will hamper the plugs ability to transfer heat from the plug to the cylinder head that is supposed to happen to make the plug run cooler.

Is this engine reliable?

[@odysseyusa]

So far, it seems reliable for most people. Both the 3.6 and the 2.0 have had some outlier type issues. IE- Valve ticking or worse in the 3.6 or the water pump outlet bolts being loose on the 2.0…or worse. Neither is “common” though. There’s a TSB for the 2.0 outlet bolts if you’re still under warranty. Otherwise, Torque them to 97 in lbs. I tightened the top with a torque wrench, barely. But had to turn it again by hand to get an idea how tight that is because the bottom bolt, I couldn’t get that small torque wrench up there. I did remove the bolts and added blue thread locker as well. There’s a few 100k plus 2.0’s out there. One guy claimed over 200k miles already!
