Description
Engine temperatures spike under sustained load, reducing efficiency and accelerating wear on critical components. The BOYESEN WPK-09M water pump cover and impeller assembly increases coolant flow across all RPM ranges, keeping your engine operating at optimal temperature and extending component lifespan. The patented nautilus-style impeller design maximizes hydrodynamic efficiency while the investment-cast construction delivers the durability required for both street and track applications.
