PERRIN 93-14 Subaru Impreza (Incl. 02-14 WRX) / 04-21 STI (w/o AC) Lightened Crank Pulley - Blue

This Perrin lightened crank pulley is made from a solid billet aluminum construction, which helps reduce rotational mass on your engine's crankshaft. By shedding weight here, you can see an improved engine response, especially at higher RPMs. It's a popular choice for Subaru owners looking to get a little more zip out of their engine without going too deep into engine modifications.

The pulley is anodized blue for a clean look under the hood, and it's designed to be a direct replacement for your factory crank pulley. While it's a lighter part, it's still built to handle the demands of daily driving and spirited runs. You'll notice the engine revs up a bit quicker, making it feel more responsive when you get on the gas. It's a straightforward swap that can make a noticeable difference in how the engine feels.

This pulley is designed for Subaru models without air conditioning. If you're looking to shave a bit of weight and improve throttle response, this is a solid option.
