Boyesen Supercooler water pump cover and impeller kit, black — Honda CRF 450 2009–2016

Description

Boyesen Supercooler water pump cover and impeller kit, black for Honda CRF 450 2009–2016. Investment-cast aluminium water pump cover with a larger, patented nautilus-style impeller — the pump moves more coolant at all rpm, so the engine runs cooler and at a steadier temperature. Most useful for enduro riders in slow terrain where engines overheat easily.
