Supercharger Pulley Upgrade Details

The crank pulley, also CNC machined from lightweight billet aluminum, is available in a bolt-on 187mm diameter, increasing the supercharger's speed by 15.4%. Both pulleys are designed to enhance power output and improve efficiency. The kit includes a full set of mounting hardware for easy installation.

This kit is an ideal choice for performance enthusiasts seeking a noticeable power boost. While the kit is designed for the specified Audi models, it also requires the APR Ultracharger Throttle Body Upgrade to achieve maximum performance benefits. With the included belt and anodized black finish, this kit offers a seamless integration with your vehicle's existing components. The APR Performance Limited Warranty ensures your investment is protected.
