I just picked up some plugs today from NAPA and they are NGK V-Power. I talked to the autoparts guy whom advised that he was pretty knowlagable on Jeeps and he only recommended the NGK's.

I was under the impression that everyone was running Champions, but when I asked him he advised that OE now recommends NGK.

Whats the deal?

 

Dunno I run Champion plugs..NGK's are still good plugs. As for OE dunno would have to ask a Jeep mechanic or call the stealership..

 

I could do that, but I usually trust the NAPA guys a little more than the other auto parts stores.

I have ran NGK's plenty of times, but that was in Hondas....

 

Run em and see..they aren't going to hurt the jeep.

 

Yea, why not. They were only $2 ea.

 

I learned this a long time ago...

Doesn't matter what anyone says, Chrysler/Jeep/Mopar whatever LOVE their Champion plugs...

The only, and I mean ONLY time I found a Chrys. that liked something different, what my old B250 Van w/ a 318. It loved the hell out of AC-Delco's, but I used Champs in it also. I tried:
Bosch
Bosch Plats
NGK
AC-Delco
Delco Rapidfires
Autolite
Denso

..in the Jeep...
Champions work the best.

 

Why is this? Does it idle / run better? Better MPG's ?

Went to the parts store today and they actually had the Champs for $1.50 ea. Mine seems to idle a little rough, wondering if the Champs will do any better for it?

 

i run the bosch platnum plugs..the last longer then just a regular plug.

 

the 2000 came stock with ngk's i tried the autolite's and it ran worse so i just use the ngk's factory plugs when i do a plug change.

 

I will put it to you in these terms....

I sell NGK's as part of my business....

My XJ runs Champions...

Idle is smoother and starting seems a touch easier.

 

Yea, I think the newer ones came factory with NGK's and the older ones Champions.

I love finding this stuff out AFTER I install the wrong part.....

 

jeeps really want what the factory gave them. up untill the later models, champion is the only plug to use. many problems with other plugs, and the older ones are not designed for platinum at all.

if its a newer one find out if it had ngk or champ and go with that. not untill daimler got real involved did this change

 

I'll say this when I put my new motor in I put Accel plugs in and they sucked. Replaced them with Champion truck plugs and the jeep ran much better. That's in a 91 with a reman engine with around 5k on the motor.

 

I am running autolite platinums right now but I think I may try champions next. The autolites are fine from what I can tell.

 

champions are good. My old explorer liked those the best also. Tried double platinum, they were ok. Never got around to tryin iridium plugs, may try them on my new jeep.
