APR 12-18 Audi A7 Quattro 3.0T 187mm Crank Pulley

APR's Supercharger Drive and Crank Pulley Upgrades dramatically increase horsepower and torque by increasing the rotational speed of the factory supercharger. APR's Stage II Pulley ECU Upgrade makes the necessary engine management adjustments to handle the increased supercharger speeds, and in turn allows the engine to create more power. The pulleys are sold separately, allowing for multiple levels of performance, each of which builds upon the other. Finally, when combined with APR's Ultracharger Throttle Body Upgrade in a dual pulley setup, the system is alleviated of power robbing inlet restrictions, allowing the engine to achieve exciting new levels of performance! Fits Audi A6 Quattro 09-18, A7 Quattro 12-18, A8 Quattro 13-18, Q5 13-17, Q7 11-15, S4 10-16, S5 10-17, SQ5 14-17​ Please note, specific software is required to maximize output with this product. A new belt is required. Use part number RS100003 with a factory supercharger drive pulley and part number RS100002 with an APR supercharger drive pulley.
