Hey Hotrod just to clairify you are suggesting I replace the new AC's I installed? I have had them out since I've tried to start it and they still look good. They are gapped @ 0.43". He bought the shorties as he is running headers and it is close clearance, and the coil was on the car when he got it. If it was a matter of new plugs I would do it, just want to be sure.
