I have the bosch supers in my 72. These have 3 electrodes, so 3 times as much power-right?. Once i had 180 hp now I have 3 times that. Yee haaa.
Actually, I use to foul plugs years ago when i was learning how to adjust the mfi. Went to these plugs and now no more fouling. I just got hooked on them. Since there 5 bucks a piece, they must be better! Yea right! Going to try the ngk's the next time to see if anything changes.
Slap those babies in, I'm sure they can't do any harm.
