Greddy USA

This GReddy Oil Cooler adapter is the correct way to run an oil cooler for an engine not originally equipped with one from the factory. The most important part is the built in thermostat, which allows for proper regulation of oil temperatures, thus giving proper oil circulation, and longer duration and service life. The initial thermostat opening is 185 degrees F, and will close after dropping below 160 degrees F
