Description
Engine temperature management directly impacts performance, reliability, and longevity—especially under sustained load or competition conditions. The Boyesen WPK-09B upgrades your cooling system with a high-flow impeller design that increases coolant circulation across all RPM ranges, keeping your engine running at a stable operating temperature. This means better thermal efficiency, reduced hot spots, and extended engine life.
Built with an investment-cast aluminum construction and featuring Boyesen’s patented nautilus-style impeller geometry, this water pump cover delivers measurable hydrodynamic improvements without requiring engine modification.
