Description

The Mishimoto Racing Thermostat is a direct fit for the 2008–2009 Pontiac G8 6.0L. It promotes greater cooling efficiency by significantly decreasing high engine temperatures. This thermostat opens at a lower temperature (160°F) than standard thermostats, allowing coolant to flow through the engine sooner and reducing engine temperatures. Mishimoto offers a Lifetime Warranty on this product.
