* 2 piece cast aluminum construction * Oil filter access for hassle free changes * Patented Nautilus style impeller for more efficiency and flow at all RPM ranges * Magnesium colored powder coat finish Note: Image for reference only. Product may vary in color and size depending on vehicle.
…temperatures and more power in the late stages of a moto * Relaxed bends and enlarged outlets to eliminate hot spots resulting in as much as 20 lower water temperature compared to stock covers Note: Image for reference only. Product may vary in color and size depending on vehicle.
…machined billet aluminum * Strong, lightweight and durable to provide outstanding protection and performance * Designed with an impeller to increase water flow and reduce hydraulic friction and cavitation * Includes impellerNote: For part# 997-WPK04250 replacement O-ring, order part# 997-PC40080401.
* CNC machined aerospace quality stainless steel impeller won't distort when hot, unlike the stock plastic impeller * Designed to slow flow through cooling system to keep coolant in the radiator longer for cooler operation * A must for hard riding through muddy terrain that can clog radiators
* Cast aluminum construction * Increased coolant flow in all RPM ranges * Patented nautilus style impeller for Hydro dynamic efficiency Note: Images are for reference only. Image shown may not represent specific model/color.
* Designed to increase water flow throughout the cooling system * Boyesen reshaped the impeller fins with an airfoil like design to reduce cavitation and to get the most water flow from the impeller * Use in conjunction with Boyesens waterpump cover to substantially decrease engine temperature
…more spark advance for increased torque * Reduces rust, corrosion and electrolysis of all metals * Cleans and lubricates waterpump seals * Prevents foaming * Complexes with hard water to reduce scale * 12 oz.
* Reduces hydraulic friction and cavitation to enhance the performance of the engines cooling system * Increases coolant flow * For use either on older models or as Sup Note: Image for reference only. Product may vary in color and size depending on vehicle.
* Durable, CNCd (Computer Numerical Controlled) and formed 5052 aluminum construction * Provides extended coverage to protect the waterpump, the engine case and the oil line * TIG welded * Easy bolt-on installation * Replaces the vulnerable stock plastic guard * Made in the USA
* Patented Nautilus style impeller for more efficiency and flow at all RPM ranges Note: Image for reference only. Product may vary in size depending on vehicle.
