Supercooler Water Pump Kit - KTM/HQV 450-501 (2017-2023)

Boyesen's Supercooler Water Pump kit features 'Hyperflow Integration' or "HFI", which is their holistic approach at efficiency and flow improvement for the engines' water pump system. Boyesen has spent years in research/development of HFI to correct in-efficiencies and production based limitations that are found in stock water pump designs. So what does this design process really translate to? 

A smoother interior surface to eliminate coolant flow "pinch points." Maximum sized inlets which not only are larger than OEM but also eliminate un-necessary bends which are a hydrodynamic no-no. Lastly, A "Proflow" High Output Impeller increases flow rate and virtually eliminates cavitation while demanding less parasitic loss from the engine. Boyesen's HFI design provides superior flow rates, increased hydrodynamic efficiency, and excellent heat management capability that makes this Supercooler Water Pump Kit the best performing system that you can buy.
