Just curious bout what kinda plugs u guys are running I no being a Chrysler OEM would be champion but ne luck w other brands I used to run Bosch platinums +4 in my pickup till it burned to hot and caused my piston tp melt so I stay away from them any input is appreciated

 

Champion coppers, my 4.0 rejected the Bosch coppers the previous owner put in the night before I bought it.

 

I have Accel Tune up kit on my 99 runs great. Really nice wire set. Had Bosch cap rotor and wire set, champion plugs on my 91 not bad either. Just more expensive, paid $68 for all Bosch/Champion stuff from Auto zone. I got the whole accel kit for $55 free shipping from summit.

 

I'm running Champion RC12PEC5 Platinums in my 2001, and it runs great. The previous owner had some Bosch 6717 in there, which also ran the car fine. I just replaced the plugs to reset my maintenance intervals.

 

Champion copper ftw

 

Bosch Platinum +2's. I won't run any other kind!

 

Running Bosch platinums as well. Purrs beautifully.

 

Autolite Iridiums, runs great.

 

NGKs in all my Jeeps.

 

I wouldnt run autolite or chanpion in anything. NGK all the way!! in both of my jeeps

 

cheap....very cheap auto llight. runs great

 

Super turbo-fire quad nuclear-tipped flame blasters with magnetic pulse-alignment technology. They're belt-driven.
I'll now be getting 400 miles per gallon. While parked. On the highway they actually scavenge exhaust fumes from the air and turn them back into gasoline, filling my tank as I drive.


Eh. or plain old boring NGK copper cores.

 

I tried Champion Copper, Bosch and have settled on NGK V-Power which my setup seems to like best.

 

I heard the next E4s are goin to be gear driven for reliability!

I run what the sticker on the firewall says. However Chrysler has superceded the Champion coppers with NGK coppers in some situations.

 

I also did the Accel tuneup kit off Amazon. Did the whole thing in about 20 minutes and it runs noticeably better.
