for some this might seem an elementary question, but i wonder whether i should use the sparkplug terminal post caps or not. the things that screw onto the ends of the plugs.
i just got a new set of plug wires and i don't want to waller out the mating part of the plug wire caps. but i did read somewhere, maybe in clymer's, about installing the screw-on post caps. so i'm not sure about the accepted procedure.
thanks in advance for your advice,
