Hey everyone I am getting ready to replace my Spark plugs and i just wanted to get an idea of what everyone is useing in their rigs. This is a daily driver 2003 TJ with a 4.0L. If you could let me know what you are putting in and how they are doing for you.

I've always liked Autolite and Bosch.

I'm in the process of replacing my distributor, wires and plugs as well for the new Unichip I just bought. When I asked the programmer which plugs, he said "Run Champion plugs as per the factory specs...you can increase the spark plug gap a little bit more though-maybe an extra .010 over stock." Maybe it's just due to the Unichip. Any other opinions?

go champion on mopar engines. ive seen alot of dyno sheets with spark plug changes. regular copper truck plug spark plugs work the best. I wouldnt mess with the gap, just keep it stock.
02 Tj with a few mods

champion works great in my 95 jeep cherokee, i just bought this used jeep and it still needs a little work but the owners manual said champion and thats what i got. the guy down at the auto parts store said that with my jeep being a 95, that i dont need those expensive plugs just regular champion plugs.
