Overview
The Perrin Water Pump Pulley is a precision-engineered upgrade designed for Subaru owners looking to reduce parasitic drag and improve engine response. Crafted from lightweight 6061-T6 billet aluminum, this pulley replaces the heavier OEM component, reducing rotational mass and allowing your engine to operate more efficiently. It is compatible with a broad range of Subaru models including the WRX, Ascent, Forester, Legacy, Crosstrek, Outback, and Impreza from recent model years, making it a versatile choice for enthusiasts focused on performance and reliability.
Engineered with a focus on quality and durability, the pulley is CNC-machined for exact fitment and finished with a durable anodized blue coating that resists corrosion and wear. Perrin’s commitment to precision manufacturing ensures this pulley maintains OEM-level reliability while delivering a tangible performance benefit. The direct replacement design means it installs easily without modifications or special tools, preserving the integrity of your engine bay.
By reducing the weight of the water pump pulley by approximately 0.28 lbs compared to the stock unit, this upgrade decreases the load on your engine’s accessory drive. This reduction in rotational mass translates to quicker throttle response and slightly improved efficiency, benefits that Subaru enthusiasts will appreciate both on the street and during spirited driving. The anodized finish also adds a subtle visual enhancement to your engine bay, combining form and function in one package.
