After reading this post I have to say I love my Jeep... no distributor. ;D
Not to jinx you, but coil packs die too!
yeah, and jeep didnt use coil packs...they used a coil rail that has the 2 coil packs molded into one rail. so if one goes you are out $225 to replace it. ask me how i know.
Why did you have to tell me that, where did you get this info? I have been a Champion Hater for years. If your info is good I will give them a try though.
mark, the 4.0L was designed on champion truck plugs. thats what came in them from the factory until they switched to the distributor-less ignition (in 2000 i think). then they started running ngk plugs from the factory. the best plugs to run in the newer distributer-less ignition are the autolite app985. they have a platinum tip and electrode. single platinum plugs (with only the tip being platinum) will make the distributor-less ignition 4.0L run like shit (and vice-versa). ask me how i know.
mine was said to gap .030 and i will definately go get some champions hopefully today i got a big rugby match today up at life University.so maybe tomorrow.
sorry matt, yeah, the gap for the distributer-ed 4.0L is .030" but for the newer ones its .035". I forgot. hope this helped.
