Description
Engine coolant flow directly impacts operating temperature stability and component longevity. The BOYESEN WPK-18AB water pump cover and impeller assembly uses a patented nautilus-style impeller design to increase coolant circulation across all RPM ranges, keeping your engine running at optimal temperatures under sustained load. This investment-cast aluminum combo is engineered to reduce thermal stress and extend engine life—critical for both track and street applications where temperature consistency matters.
