DETAILS

Upgrade your Subaru’s cooling system with the Mishimoto Racing Thermostat, designed to keep modified and turbocharged engines running cooler and more efficiently. Unlike the stock thermostat, which opens at 172.4°F, the Mishimoto thermostat opens at 154.4°F, allowing coolant to circulate sooner and prevent high engine temperatures under demanding conditions.

Features:

Lower Opening Temperature (154.4°F vs. 172.4°F stock) – Reduces and maintains optimal engine temperatures, especially for modified or turbocharged setups
Enhanced Cooling Efficiency – Promotes consistent coolant flow throughout the engine for improved reliability and performance
Direct Fit Replacement – Easy installation with factory compatibility

Keep your engine protected and maintain peak performance with a thermostat engineered for spirited driving and high-performance applications.

Great product. Works/cools my subaru a lot better then stock. I have one in my 2002 bugeye. It's been in my car for a few years now and still working like new. This one I just got went into my subaru and same results basically.

Very nice thermostat

Install was very simple, gasket felt nice, worked better then expected and packaging was awesome. Car ran around 163-170° for a 30 minute drive

We are glad the installation was simple and that the gasket felt solid. Enjoy the upgrade and thank you for your 5 Stars!

Works wonders

Works as designed, if not better. Noticed immediate difference and results. Word to the wise though, can cause check engine light if you have no MAP loaded. Installed on my stock STI and got a CEL once or twice since it takes longer to get up to temp.

Conner,

It is great to hear that the Mishimoto Racing Thermostat is delivering noticeable improvements in performance for your STI! Thank you for sharing your 5 Star Review and experience!

Regards,

Works so good
