Mishimoto Racing Thermostats are engineered to be very effective in lowering engine temperatures and feature high-quality wax and quality rubber seals for a leak-free operation. These thermostats open at slightly lower temperatures compared to OEM ones, allowing the coolant to flow through the engine sooner. This helps in reducing and maintaining cooler engine temperatures. Mishimoto thermostats will offer optimum engine cooling, whether you are a daily driver or you have a modified and upgraded turbo on your vehicle.
