Killer B Water Pump Inlet 2002-2007 WRX/STI

Killer B’s Water Pump Housing is a much more robust design. Designed using state of the art 3-D CAD software to assure maximum flow with minimum turbulence for the best performance possible!

Install note: The inlet is slightly longer than the stock one, so you will have to trim the lower radiator hose accordingly.

Specify just the inlet, or a full kit that includes the lower radiator hose, cut-proof clamps, and gasket.

Fits all 2002-2007 Subaru WRX, and all 2004-2007 WRX STI.
