Dani, Just go with regular old Bosch single-electrode plugs. Most owners have found that properly gapped basic plugs seem to work better than the fancy stuff. You can find the correct ones on Grady's site. Andy In a message dated 4/17/2010 9:55:35 P.M.

I'm looking at John's 25,000 volt Bosch coil [as an upgrade?] since I doubt the stock one has that much punch to it. I have +4 plugs that are a little old but few miles and are still in good shape; also Johns 8mm wires and upgraded resistor. I once used the blaster coil with my setup but I remember having problems with it - I believe it was melted distributor rotor but can't remember correctly. Nonetheless, with what I have as far as plugs, wires and resister; which coil should I be going after? My engine runs like garbage when it rains, and when it is dry it sputters at stops from time to time and just doesn't feel "right".
