Perrin Water Pump Pulley (Blue), 2015-2021 WRX

PERRIN Lightweight Water Pump Pulleys weigh 0.48 lbs, which is 0.28 lbs lighter than 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 an engine frees up horsepower to send to the wheels. With that in mind, the PERRIN Lightweight Water Pump Pulley replaces the OEM water pump pulley with a lightweight, high-performance version.
The PERRIN Lightweight Water Pump Pulley is machined from 6061T6 billet aluminum. Featuring an anodized black, blue, or red, finish and laser etched for increased belt life and a precision fit.
