External Thermostat

Proper warm up and bypass protection

We carry the '74-'89 style factory 911 thermostat. Superior to aftermarket units, this thermostat includes a pressure bypass valve. In the event the oil cooler loop gets blocked and cannot pass oil, the bypass valve opens allowing oil flow and protecting your engine from oil starvation.

This unit can be retrofit to all 911s from '65 to '89 and 914/6.
