plugs
Ive always gone with plugs made by the man. Its usually one less thing to worry about. The regular ones not IR/PT or $$.
I had an interesting thing happen when trying "rapid Fire" GM plugs in an old 2.8. The car started to miss occasionally and the last thing I suspected was the plugs for they were new.
There was one plug which had the insulation crack and slide down the electrode like a turtleneck. It taught me to always suspect the plugs as they are in a pretty high wear place and can fail.
