This may sound like a very simple question, but I'll ask anyway. I rebuilt my 2.4 motor about 12 years ago. I used S pistons and E cams with carbs. It ran great. I then removed the motor for storage while I restored the old 911. I removed the plugs so I could turn the motor over by hand every couple of months. Well, I've lost the plugs and have no idea what type or heat range to use. I'm about to put the car back on the road and need some advice. Thanks, Rich Lorenz

I would go with the spark plug recommended for a S of your year,and as far as a type I would stay with a Bosch or NGK standard copper plug.

Hi Rich:

You cannot go wrong with Bosch W5DC's for street use. The Bosch W5DS silver plugs last longer but cost more.
