Great upgrade

Bought this while building my engine out of my STI. Before I had issues of the coolant temps sitting pretty high but this helped improve the flow of the coolant which has helped bring the coolant temps.

Zack,

Thank you for your 5 Star Review! We are thrilled to hear the Killer B Water Pump Housing improved your coolant flow and temperature management.

Staying cool

Doing a radiator upgrade so figured I'd do this at the same time. The part is straight forward and fits great.

John,

It is great to know that the installation was straightforward and the fit was perfect. We appreciate your support and hope you continue to enjoy a cooler ride!

Smoother delivery

I picked up Killer B’s pump housing because I was installing some key reliability mods on my ‘19 STi. Install was a breeze! Just two bolts. Of course I replaced the one-time-use thermostat gasket while installing to ensure a proper seal for the smooth delivery of coolant. If you’re replacing your coolant hoses and radiator, might as well pick this piece up as well!

Killer B never fails!

When I got it, it surprised me how much bigger it was then the OE one. it does work with OE size lower hose. if you haven't done or planned it i would recommend replacing the thermostat, and seal with OE products. the product bolts right up and is super easy! also remember to use blue coolant in your EJ!!
