They look good but I still have misfires...?
I use NGK plugs in my racecar motors, so I know they are really good quality. These look really nice, and the gap was already perfect, so I didn't have adjust. However, I am still having intermittence misfires in my Harley Softail 103...? My old plugs were looking normally aged, but I didn't know exactly how many miles on them (bought bike used) so I figured it was time to change them. I still have the same misfires, so I can't say for sure it could be these plugs...? I have used fuel injector cleaners, and almost always 93 octane fuel, so I need to try to figure out why it is still bucking occasionally... hopefully not the injectors or ECM... :O(
