Perrin Red EJ Alternator Pulley 2004-2006 STI

Constructed from high-quality materials, the PERRIN Alternator Pulley offers a matching signature crank pulley design and decreases rotational weight, yet maintains a good aesthetic. Weighing only 0.116lbs, this pulley is lighter than the OEM alternative. With this easy-to-install part, drivers can expect an increase in throttle response, horsepower, and torque of their 2004-2006 Subaru WRX STI.
