APR Audi A6 Quattro Supercharger Pulley Kit – 57.75mm Press-On (Black), 2009–2018. This drive pulley reduces the factory diameter to increase supercharger speed and unlock stronger performance with proper software.

By shrinking the stock ~63.25mm pulley to 57.75mm, blower speed rises by about 9.5%, improving response and torque across the rev range when matched with APR’s Stage II Pulley ECU Upgrade. The CNC-machined billet stainless pulley is e-coated black for an OEM look and is designed for press-on superchargers. For bolted units use part MS100139; a removal tool MS100025 is recommended. A new belt is required: RS100001 with a factory crank pulley or RS100002 with an APR crank pulley. Fits 2009–2018 Audi A6 Quattro 3.0 TFSI.
