Boyesen WPK-45O Orange Supercooler Water Pump Cover & Impeller Kit - High Performance Cooling Upgrade for Dirt Bikes & ATVs - Perfect for Motocross, Trail Riding & Off-Road Racing

By casting a totally new water pump cover, Boyesen was able to maximize the flow through the unit. Boyesen's design takes advantage of everything from Bernoulli's Effect to biological studies. Unlike the stocker, Boyesen's water inlet has an increasing diameter and artfully curved shape. This is a vast improvement over most stock inlets, which decrease in diameter as they near the impeller and have a 90-degree bend at the pump. Patented nautilus style impeller for hydrodynamic efficiency, reducing heat, gaining horsepower and extending engine life. Can reduce engine temperatures by as much as ten degrees . Fits: KTM 450 EXC 12-15, 450 SX-F 13-15, 450 XC-F/W 12-15, 500 EXC 12-15, 500 XC-W 12-15; Husqvarna FE501 13-14, FC450 14-15, FE450 14-15; Husaberg FE450 13-14, FE501 13-14.
