BEGi took out my thermostat last year and lost it. Finally putting the motor back together and need to find a replacement one with the rubber gasket that comes with it. Does anyone know the part number for it? The normal miata thermostat has an offset opening so it hits the external housing. The m-tuned one is centered.

 

call m-tuned?

 

It's Sunday. They're probably closed.

Yep... http://www.etdracing.com/m-tuned/contact_us.php

 

I've seen those on t-stats at VatoZone or O'Reilly. Do you really need it or will the water pressure take care of the not-so-important perfect seal here?

Thanks for the link. Looks like they are using a stock thermostat but supply a rubber gasket that goes around the outer edge.

Hustler, I had a similar thought but the thermostat is pretty loose in the housing without the rubber seal. Not sure if it would get stuck at an angled position. Guess I'll call M-Tuned tomorrow. Bah.
