Description
Engine cooling efficiency directly impacts performance and longevity—inadequate coolant flow leads to temperature spikes that compromise power output and accelerate wear. The Boyesen WPK-26B water pump cover and impeller upgrade increases coolant circulation across all RPM ranges, maintaining optimal operating temperatures under sustained load. This investment-cast aluminum assembly uses a patented nautilus-style impeller design that reduces parasitic drag while delivering measurably higher flow rates than OEM components.
