I've been trying to figure out what spark plugs go in my M37..

I've seen here and there on the internet these different ones listed as "the ones" for M37s..

2245
2243
2344

Can anyone resolve this? I'm gettin' dizzy.

Oh, and once the correct ones have been selected, anyone know the gap?

Thanks millions!

The old PS magazines are online now and have a couple of great articles on the "hot", "cold", and "normal" spark plugs for the M-37. The link to the site is below.
