Description

BMW E36 (92-99) Mishimoto racing thermostat 68 °C

The Mishimoto thermostat E36 is a racing thermostat for the six-cylinder BMW E36 from 1992 to 1999. Where the original thermostat only opens at 88 °C, this one opens at 68 °C. Coolant starts flowing through the radiator earlier and the engine stays cooler.

This is especially noticeable on tuned engines, turbo or supercharger builds and during long sessions on track or while drifting. A small change that gives the whole cooling system more margin, especially combined with a larger radiator.
