Hmmm... my M30s dont have throttle heaters and I don't have any issues even in single digits... Aside from lack of traction...

Only certain cars have it. M20s, M42s, M44s, M/S50s, and M/S52s. And of all those only M20s have those stupid cork gaskets. The rest all have the chamber cast into aluminum so they never have problems.

its a $1.26 item and of the above mentioned engines the m20 is the oldest design listed.

The M30 dates back to WWI though, its based on an airplane engine... Before airlplanes had 1500hp+ crazy man engines (WWII).

Or so I have heard...
