I used to thing they were crap too, but it is what Jeep put in there OEM, so I stuck with them, and they work perfectly.

I don't know factory recommended but for what its worth i recommend NGK spark plugs. I have buddy that does desert racing and thats what he uses in his buggy and all my friends use them in their 4x4's

This is where I order them from.

Just plain jane champion plugs. Seriously.... it's what came from the factory and what i run in mine. Never had much faith in them until i bought my first jeep. IMOP they are the best bang for your buck.

alright. good to know since this is my first car I've had to buy more than 4 plugs on. also, has anyone ever done the swap from strap-style u-joint retainers to u-bolt style? whats involved in this swap? i assume you have to drill out the bolt holes in the yoke
