Product Description

The Perrin PSP-ENG-112BL is a lightweight water pump pulley engineered as a direct replacement for the OEM unit on 2022-2026 Subaru WRX, Outback XT, Forester XT, Impreza, and Crosstrek models. Machined from 6061T6 billet aluminum and anodized in blue, this pulley weighs 0.48 lbs compared to the factory pulley's 0.76 lbs, cutting 0.28 lbs of rotational mass from the engine's front accessory drive.

Reducing rotational mass frees up horsepower that would otherwise be spent spinning heavier factory components, translating into a noticeable improvement in throttle response felt with every blip of the pedal. The pulley surface is laser etched to improve belt grip and extend belt life, while precision machining ensures a proper fit against the OEM water pump and drive belt.

This pulley is intended for owners looking for an easy, direct bolt-on upgrade that improves engine responsiveness without any tuning or modification required elsewhere. Installation takes about 30 minutes with basic hand tools, and the pulley is backed by Perrin's 5-year warranty.
