Default coil on plug ????

I have already swaped out my plugs (not that bad with right tools) does anyone make a aftermarket coil on plug thinggys? If i buy 4 new ones might as well and see if there is an upgrade. or figure out some way to test each one.

Your only hope is to custom make your own and I think there are instructions on scoobymods on how to do it. You will end up netting .00034HP for all your efforts though.

Awhile ago, MSD tested the ignition system and didn't feel it was worth it to build an aftermarket one because it was so good.
