i tried the bosch +4 thingys, they made my jeep run like a 3 legged dog on acid..
brand new set of champion copper cores are the best from what i've heard, BUT i've also been hearing about NGK plugs lately and that they're supposed to be very nice to jeep engines as well. i bought a set of NGK's from autozone about a week ago but i'm still waiting for the damn heep to come back from the dealer (grenaded rear end) to give them a try.
