2022 WRX Perrin Alternator Pulley Blue

This lighter pulley is great with the other lightweight Perrin pulleys. Not only does it look good, it performs great and helps the motor rev faster. I like it and the harmony of the motor is intact.

Adrian,

You said it all! Thank you for the 5 Star Review of the Perrin Alternator Pulley!

Regards,
