Boyesen Supercooler Water Pump Cover & Impeller Kit – Magnesium
The Boyesen Supercooler is a 2-piece cast aluminum water pump cover and impeller kit specifically designed to enhance the performance of your engine’s cooling system.
- Cast aluminum construction
- Oil filter access for hassle-free filter changes
- Increased coolant flow at all RPM ranges
- Patented nautilus style impeller for hydrodynamic efficiency
By casting a completely new water pump cover, Boyesen was able to maximize coolant flow through the unit. The water inlet features an increasing diameter and artfully curved shape, an improvement over stock inlets that decrease in diameter near the impeller and include a 90-degree bend at the pump. The patented nautilus-style impeller is designed to reduce heat, and extend engine life.
