Re: Autolite spark plugs in 4.0 L Jeep
 

Ditto on the Autolite platinum plugs. That is what I will stay with in my
4.0L.

I used Autolite plugs for many years before trying both the Bosch Plus4 and
the Spitfire plugs. Neither one measured up to the Autolite plugs in this
engine, so I'm back to the Autolites.

Funny, I was told the Champion Truck Plug was the best thing to put in my
2.5L. I thought I heard that from some people on this list, actually. I
haven't pulled them since installing them, so I don't know what they look
like.
