Audi SQ5 Supercharger Pulley Kit - APR - 57.75mm Press On Underdrive - Black - 2014–2017. This APR drive pulley reduces diameter to 57.75mm, increasing supercharger speed for stronger, more responsive performance when paired with the proper software.

Engineered for the 3.0 TFSI with a press-on hub, it replaces the factory ~63.25mm unit and spins the blower about 9.5% faster across the rev range. The pulley is CNC machined from billet stainless steel and e-coated black for a factory look and durability. For best results, use APR Stage II Pulley ECU software; a new belt is required, and a pulley removal tool is needed for installation. This kit is intended for press-on applications only on 2014–2017 SQ5 models.
