Audi A8 Pulley Kit - APR - Dual Pulley with Belt - Black - `15-`18. A dual-pulley upgrade for the 3.0 TFSI A8 that increases supercharger speed for stronger, more responsive performance with proper tuning.

Developed by APR, this kit pairs a 57.75 mm supercharger drive pulley with a 187 mm crank pulley. The drive pulley is CNC machined from billet stainless steel and e-coated black; the lightweight crank pulley is billet aluminum, anodized black, and bolts over the factory harmonic balancer with new hardware. Together they yield about a 26.4% supercharger speed increase over stock for broader torque and improved acceleration. Specific software is required to maximize output (sold separately). A correctly sized belt is included.
