PERRIN Performance has released a lightweight water pump pulley for the 2015 WRX with the 2.0L engine. Reducing the weight of rotating parts inside and outside an engine frees up horsepower that can now be sent to the wheels. With that in mind, the Lightweight Water Pump Pulley replaces the OEM water pump pulley with a lightweight, high performance version.
