Can someone tell me what plugs are suitable for a '54 G9

Its got Champion N5C's in at the moment but I've always used NGK, so is B6ES correct? Also what plug caps should I use?

Many members use the B7ES plugs and you must not use plug caps that have resistors built in them, they reduce the performance of the magneto.

Mike is right! On second thoughts-my estimate of 500 hours is far to short!! {only joking!}
