Torque Solution Lightweight Alternator Pulley (Black): Subaru EJ WRX 06-14 / STI 07-21

Torque Solution is known for making well-built performance parts for Subaru vehicles. This lightweight alternator pulley is a direct replacement for your WRX or STI, designed to reduce rotational mass on the engine. By shedding some weight from the alternator pulley, you can help your engine rev a little more freely.

This pulley is made from aluminum for a significant weight reduction compared to the stock steel or cast iron pulley. It's finished in black to give your engine bay a cleaner look. Installation is straightforward, as it bolts directly in place of the original pulley. It's a simple way to make a small but noticeable change to the engine's response.
