Copper or Platinum plugs for use w/MSD?
Right now I'm trying to decide between changing my plugs to NGK Coppers or sticking with the Bosch Platinum +4's that I have in the R now. I heard platinum plugs are better for high RPM spark, is that true, and that copper plugs help throttle response, is that true? TIA

MSD ignition heats up everything - platinum plugs run hot w/o upgraded ignition, therefore go NGK, go copper. I know, I am running an MSD ignition, BTW - I likes!
As for Bosch's Platinums increasing poines at high RPM's, it's dyno'd proven, but only 1 hp or less. So who really cares, plus honda's need low-end power anyway, stay NGK...
