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

This Perrin crank pulley is made from a solid billet aluminum construction, which helps reduce rotational mass on your engine. Less weight spinning means your engine can rev up a bit quicker. It’s designed to fit a range of Subaru models, including the 1993-2014 Impreza (which covers the 2002-2014 WRX) and the 2004-2021 STI models, as long as they don't have air conditioning.

By shedding weight from the crankshaft, you'll notice a slightly improved throttle response, especially when you're accelerating from a stop or exiting a corner. While it's a lighter part, Perrin still builds these to handle the demands of daily driving and spirited use. The black finish gives it a clean, understated look under the hood.
