§ 02 / About this part
What it is
The BOYESEN WATER PUMP COVER & IMPELLER KIT SUPERCOOLER ALUMINUM MAGNESIUM, water pumps. Stocked by Iron Offroad, the UK MX hard parts specialist.
Standard pumps often suffer from cavitation at high RPM. This kit increases coolant flow by optimising the hydrodynamic surface of the impeller. It sits on the side of your engine case. Increased flow reduces engine temperatures during heavy sand motos or technical hard enduro climbs. This is a direct replacement for your OEM housing and internal impeller. Ensure you drain the cooling system fully before installation. Use a fresh gasket to maintain a proper seal against the crankcase.
