Product Details
If you're looking to keep your Subaru WRX, Forester, or other compatible model running cooler, especially under demanding street or track conditions, a lower-temperature thermostat can make a real difference. This Mishimoto racing thermostat is designed to open sooner than the stock unit, allowing coolant to circulate through the engine at a lower temperature. This helps to reduce overall engine temperatures, which is beneficial for both stock and modified vehicles.
This thermostat activates at 165.2 degrees Fahrenheit, compared to the stock thermostat's 190.4 degrees Fahrenheit. By letting coolant flow earlier, it helps maintain more consistent and cooler operating temperatures. It's a direct replacement for your factory thermostat, making installation straightforward. This part fits a wide range of Subaru models, including the WRX, Forester, Ascent, and Outback.
As with all Mishimoto products, this racing thermostat comes with their Lifetime Warranty, giving you peace of mind with your purchase.
