HKS 03-06 EVO / 08 EVO GSR/MR 75 degree Low Temperature Oil Cooler Thermostat

If you're running an aftermarket oil cooler on your 2003-2006 or 2008 Mitsubishi Lancer Evolution (GSR/MR), managing oil temperature is key. This HKS thermostat is designed to help your oil reach its optimal operating temperature faster and keep it there. It opens at 75 degrees Celsius, allowing oil to flow through the cooler only when needed.

This thermostat is a well-built component that helps prevent over-cooling, which can be an issue with larger oil coolers, especially in colder weather or during spirited driving. By restricting flow until the oil warms up, it helps maintain consistent oil temperatures, which is important for engine longevity and performance. It's a straightforward part to install if you're already working on your oil cooler setup.
