Is there a replacement coil that is "better" than the others? The stock 6.1 coil supersedes to the hellcat coil . What about the aftermarket "performance" coils ? How about generic stock replacements?
Any and all input is welcome. Thanks
probably should have added this is 12.5 compression N/A on E85 ... race only
