The Mishimoto racing thermostat will promote greater cooling efficiency throughout your engine. The Mishimoto racing thermostat will significantly lower high engine temperature produced by modified and upgraded turbo applications. Once the engine is fully warmed up the Mishimoto racing thermostat will open up at a lower temperature than standard thermostats, also allowing the coolant to flow through the engine sooner thus reducing and maintaining cooler engine temperatures.

Works great

Replaced the thermostat, when I replaced my radiator for a 2 row aluminum one. My lifted forester was running hot with larger tires on it. Runs much cooler now with both being changed out.


Thank you for your 5 Star Review and added pic! It is fantastic to hear that the Mishimoto Racing Thermostat helped to address the overheating issue in your lifted Forester! Upgrading to a more efficient radiator and a performance-oriented thermostat can certainly have a positive impact on the cooling system's performance, especially when larger tires are involved. Enjoy your improved cooling system performance!

It was great upgrade to my Forester XT matched with new radiator noticed a big difference in performance and cooling .


When looking for the most efficient cooling, the Mishimoto Racing Thermostat will help. It opens at a lower temp, allowing your coolant to flow sooner, cooling your engine sooner. It is a simple upgrade that is totally worth it! Thank you for your 5 Star Review!

Thermostat review

I love it it works really good on my old Subaru so now I can actually have fun with the car and hopefully someday compete in a autocross race


We appreciate your 5 Star Review! The Mishimoto Racing Thermostat is the perfect way to keep your car cool! Opening at a lower temperature allows fresh coolant through your motor earlier! Autocross is a blast you will absolutely enjoy it! Good luck and have fun!

Does exactly what it's supposed to !


Thank you for your 5 Star Review of the Mishimoto Racing Thermostat! As you said it does exactly as it's supposed to, by providing better cooling, lowering your engine temps!


Fantastic cooling

Works like a charm, but I must say it is running really cool now. Might have to put the original back on. But works as advertised.


The Mishimoto Racing Thermostat is designed to open at a lower temperature keeping your engine cooler under those harsh driving conditions of the track or auto x! Thank you for the 5 Stars!
