Heat Is the #1 Enemy of 4-Stroke Engine Performance Boyesen SuperCooler Water Pump Cover and Impeller Kits are specifically designed to enhance the performance of your engine's cooling system.
These high-flow, hydrodynamic water pump kits have been tested and designed to flow more coolant.
By increasing the flow, the engine will run cooler at a more constant temperature.
The Boyesen Supercooler can reduce engine temperatures by as much as ten degrees, as confirmed by tests at Team Kawasaki.
How does the Supercooler achieve this? Hydrodynamics.
