Granatelli Billet Thermostat Housing with 160° Thermostat – 2018-2021 Jeep Grand Cherokee Trackhawk (Black)
The Granatelli Billet Thermostat Housing with 160° Thermostat is a premium upgrade for the 2018-2021 Jeep Grand Cherokee Trackhawk. CNC-machined from high-grade billet aluminum and finished in a durable black anodized coating, this housing replaces the factory plastic unit with a much stronger and better-looking component. It comes pre-installed with a 160° thermostat, which allows the engine to run cooler than the stock 180°+ unit, improving charge air density, reducing heat soak, and helping maintain consistent power output during aggressive driving or track use. The housing retains all factory mounting points and sensor locations for a direct bolt-on installation while offering superior durability and heat dissipation.
