Perrin Black Alternator Pulley 2015-2023 WRX

The PERRIN Alternator Pulley mirrors Perrin's signature design and weighs in at an impressively low 0.116 lbs. This outcome is lighter than the OEM pulley, and allows for the increase of throttle response, power, and torque that comes with this easy-to-install part. Features include construction from high-quality materials and benefits such as lighter rotating parts to free up engine power. This alternator pulley is compatible with 2015-2023 Subaru WRX models.
