my experience is as follows... i replaced all eight bad plugs with these accel plugs i saw at the local parts store. Finished the install and started her up only to have a bad miss during idle. I hooked the timing light to each wire to test for spark and found three were bad. Checked my wires next thinking the plugs are new... Wires and cap all good. I went to the store yet again and picked up the acdelco reccommended for my ride. Swapped them all and she purred like a kitten... I'm not sure if you guys have talked about them before but i figured i'd give you guys my experience if it helps... In the future i'm sticking to delcos and ngks

I used them on a 305 with headers and they all seemed to run just fine, I had no problems with them, and I still have a set laying around.

Are these plugs one heat range only? If so, that could account for some of the problems that people are having.
