Audi A8 Quattro Supercharger Pulley Kit - APR - 57.75mm Press On Underdrive - Black (2013–2018). This precise press-on drive pulley reduces the factory diameter to increase supercharger speed when paired with proper tuning.

Replacing the ~63.25 mm stock pulley with a 57.75 mm unit spins the 3.0 TFSI supercharger about 9.5% faster, providing gains across the rev range when paired with APR Stage II (Pulley) ECU software. It is CNC-machined from billet stainless steel with a black e-coat for durability and an OEM-like look. Designed for pressed-on applications; a new belt is required.
