MSV Racing '85-'04 Kawasaki KX500 High Flow Billet 7075-T651 Aluminum H2O Impeller, Main Cover Gasket and Button Head Fastener

MSV Racing offers a must have item for your KX500 Engine!

When MSV Racing applied their highly successful  OptiFlo CR500 “phi” Impeller design technology to help cool the ’85-’04 KX500, the result was an Impeller that easily out performed OEM, Mino, Frank’s MX and AS3 Impellers.

The KX500 “phi” impeller vanes are computer designed using “Golden Ratio” proportions based on the KX500’s H2O pump housing. This as well as closer tolerances between impeller and housing offer +1.2  average GPM more coolant flow. This increase in flow reduces the cycle time between the engine and the radiators allowing more heat removal quicker, lowering head and coolant temperatures up to 18*f when you need it most! 

Remember, horsepower = heat. Preventing your engine from heat soak is KEY to building and maintaining maximum engine performance. The more efficient the engine’s cooling system, the more heat (horsepower) it can handle.

Whether you’re racing Outlaw Karts, GNCC, Hill Climb, Sand Drags, Super Moto, or MX. Railing tight single track, sand dunes or just love the latest enhancement for your KX500, trust MSV Racing’s KX “phi” Impeller to help put you at the head of the pack!

The MSV Racing KX500 “phi” Impeller comes with the main pump cover gasket and button head impeller fastener for a seamless install.

Impeller kit replaces OEM parts- 59256-1065, 130CA0520, and 11009-1952
