Trak Pro 180°F Thermostat for Mazda RX-8 2003-2012

Our Thermostat for RX8's uses an on center design with a stainless steel seat that can't stick shut.

It starts to open at a lower temperature than the OEM part and begins removing heat sooner. It fully closes the bypass port providing full circulation through the radiator and the 3/16" transfer port insures air can't get trapped behind preventing it from opening. Comes with a new seal / gasket ready to install.
