Ok so I don't see any cracks in the tower or carbon tracking, my plug wires are 8mm "low ohm suppression" wires, only a few months old. My prime suspect is my cap. The brass terminals (they are brass colored anyway) have already got carbon markings on them after i just cleaned them to bare metal the other day.
Does anyone know a part # for a high quality, copper-terminal cap? Preferably the ones with the extra-wide terminals? I know the original oem ones cost a fortune, is there a decent quality reproduction out there?
