Includes housing and sealing o-ring A thermostat that opens sooner promotes better cooling in your vehicle. Running a lower temperature thermostat will keep everything much cooler. Keeping the engine cooler will help reduce and improve the life of the seals in your engine, saving you time and money, while also helping to increase engine performance. A tune might be required to gain the most from this modification, as well as to get your car's ECU accustomed to seeing lower temperatures.

If your vehicle is experiencing cooling issues, chances are the thermostat is the cause. Common symptoms include prolonged warm-up at highway speeds from the thermostat being stuck open, or consistent overheating issues from the thermostat being stuck in the closed position. Either condition can result in poor performance, and potential damage to vital components in your vehicle.
