Audi A7 Quattro Supercharger Pulley Kit - APR - 57.75mm Press On Underdrive - Black - 2012-2018. This press-on drive pulley reduces the factory diameter to 57.75mm to increase supercharger speed and deliver stronger performance when paired with the correct tuning.

Built for the 3.0 TFSI with a press-on hub, APR's CNC-machined billet stainless drive pulley is e-coated black. Reducing the stock ~63.25mm to 57.75mm raises blower speed about 9.5% and, with APR Stage II Pulley ECU software, produces a stronger, wider torque curve. A new belt is required (RS100001 with a factory crank, or RS100002 with an APR crank). Use APR tool MS100025 to remove the OE pulley. Not for bolt-on style pulleys (use MS100139).
