The Speedmaster High Flow Thermostat opens at 160 degrees Fahrenheit, promoting a cooler operating temperature that can benefit performance engines running under demanding conditions. Its high-flow design is engineered to support improved coolant circulation compared to a standard OE-style thermostat, helping maintain consistent engine temperatures during spirited driving or competition use.
This thermostat is designed for use with Speedmaster part numbers PCE191.1024 and PCE664.1001, making it a compatible replacement or upgrade component within those cooling system assemblies. Always verify fitment with your specific engine and cooling system configuration before installation.
