Best Spark Plugs for 94' ZJ????
V8 5.2 liter ZJ. What's the best spark plugs in your opinion? Just bought her a week ago. I'm in love. Any helpful advice for a newb is much appreciated. I want to start taking care of her.. On my way to the store to get a new battery, just thought I'd get a recommendation on plugs and anything else simple enough for a newb to help performance. Thanks.

I like and have had good luck with Autolite spark plugs. Don't waste your money on platinum, E3 plugs, or any of that crap. Replace the distributor cap, rotor, and wires too, you will probably ruin a sparkplug boot or two pulling them off the sparkplugs anyway.

I've only had limited experiences with about 5000 spark plugs in my life in all kinds of land, sea, air motor applications. I've used Champion since 1970 in almost all applications successfully. ( I have a buddy who says completly different). I'v also used NGK in 40% of same applications successfully. Had fouling or complete failures out of the box troubles in past with bosch, delco and motomaster brands. Agree with the earlier post on the special tip designs,(snake oil to me), straight conventional construction of the plug will work perfectly well in your ZJ.
