AC Delco Rapid Fire plugs
 

Good plugs. I changed from the Bosch +4 with the four electrodes because naturally I thought they would help. Just repalced my plugs and wow what a difference!!! Much smoother idle and better acceleration.:DVery satisfied. AND CHEAPER TOO!!!

I'll second that opinion. I just changed the plugs in my 1993 LT1 Camaro. The parts guy suggested the Rapid Fires as an alternative to the OEplatinum ones that were like $8 a piece. Went with the Rapid Fires and a new set of Taylor 8mm wires and WOW this thing really runs great. All hesitation and rough idle is gone and like you said acceleration is awesome.I would suggest these to anyone.
