Perrin Water Pump Pulley Blue 2015-2021 WRX / 2014-2018 Forester XT / 2017-2022 Impreza / 2018-2020 Crosstrek

Here, you are looking at the Perrin Performance Water Pump Pulley.

Weighing in at 0.48 lbs, this pulley shaves 0.28 lbs off of the vehicle from the OEM pulley. Throttle response, horsepower, and torque are all increased with this easy to install part. Reducing the weight of rotating parts inside and outside of the engine frees up horsepower to send to the wheels. 

It is machined out of 6061 T6 aluminum, and laser etched for increased belt life, and a precision fit. This pulley is a great way to add some style to your engine bay while shaving weight, increasing throttle response, and easing stress on your engine. 

Available in Red, Blue, or Black anodized finishes.
