2001 Spark Plug question

I searched around on spark plugs and was pretty settled on the Champion Truck Plugs. Then I read a post about Chrysler switching to the NGK plugs for later models. I have an 01 and was wondering if there was a reason for choosing one brand over the other. Thanks.

NGK.

They are higher quality than any champion.

Champion would run 5 mins and foul out in my dirtbike.

Put in a NGK, lasted years.


Champion is for lawnmowers!


Autolight is also a decent plug but I will always run NGK's

Re: 2001 Spark Plug question

I've been running NGK plugs in the 2001 for about 1.5 years now- flawless so far. They also work exactly as they should in my 1990.

Cap and rotor of course!

They go bad every few months for us. We wheel with a lot of moisture though but give it a look!

A little anti-seize on the spark plug threads to guarantee an easy change next time.

actually champions were specifically designed to run in the 4.0. I think the engineers at Jeep would konw a little more than you about this, thats why we can get 300,000 miles + out of the 4.0 with 99 cent copper plugs. As for the later models...I've never heard they switched.

Re: 2001 Spark Plug question

Stock plug for the 2001 is the NGK V-Power..part# ZFR-5N Just picked them up from the dealer. They did switch over from the champions for later models. The parts guy I deal with has worked there since before I was born.

I would LOVE to see a 300k mile champion. I don't believe that possible.

Maybe they did design the champion to work with the 4.0, I would STILL never run them.

I have NEVER had a set last more then 10,000 miles. The NGK's that are in my truck have been in there since 03' and STILL it runs like a dream.

I bet they need to be replaced, but they are still running strong!

Re: 2001 Spark Plug question

I don't think he said 300k on a set of plugs, he said 300k on a motor. Even the best, most over priced plugs can't go that long. My Oldsmobile Aurora northstar engine has 130,000 miles on it, and I just changed the stock platinum plugs last month, they looked good other than the larger gap from deterioration. I've use Accel and Champion plugs in my 4.0 XJ, both are good.

Re: 2001 Spark Plug question
