The Perrin alternator pulley decrease rotational mass and which helps to improve your performance and engine response time. Subaru models with the OEM clutch style alternator pulleys may fail over time. This failure will result in knocking noises, battery charging issues, belt wear, and cause belts to become extra jumpy. Perrin created the alternator pulley to remove this future failure point.

Easy Mod!

Easy mod once the cover of the oem pulley is off. Trick is to poke a hole in the center and then pry it off using the hole. Pulley looks great and adds color to engine bay. Hoping for a slight mpg boost too.
