Audi Q7 Supercharger Pulley - APR - Bolt On 57.75mm - Black (2017-2019). This direct-fit pulley increases supercharger speed for sharper response and stronger output when paired with the proper APR tuning.

By reducing the factory ~63.25mm drive pulley to 57.75mm, APR spins the blower about 9.5% faster. It is CNC machined from billet stainless steel, e-coated black for an OEM look, and installs with new OEM bolts on Gen 2 3.0 TFSI engines that use a bolt-on pulley. For best results, use APR Stage II Pulley ECU software. A new belt is required based on your crank pulley setup.
