Description
Stock water pumps struggle to maintain consistent coolant flow under sustained high-RPM conditions, allowing temperatures to spike and robbing horsepower when you need it most. The BOYESEN Impeller Pump CR250 (WPI-02) is engineered to maximize flow rate while minimizing hydraulic friction—keeping your engine in the optimal thermal window lap after lap. By reducing cavitation and maintaining efficient cooling cycles, this pump directly extends engine longevity and helps you stay competitive without sacrificing reliability.
