CTS Turbo 3.0T V6 Crank Pulley Upgrade Kit (180mm)

The CTS Turbo 3.0T V6 Crank Pulley Upgrade Kit features a precision-engineered 180mm pulley designed to overdrive accessory components on Audi's supercharged 3.0 TFSI engine. This larger diameter pulley increases alternator output and powers auxiliary systems more effectively under high-load conditions. Manufactured from lightweight yet durable materials, the kit suits B8 and B8.5 generation S4 and S5 models from 2010-2017, plus C6 A6 variants. The upgrade maintains factory belt routing while delivering improved electrical system performance for tuned vehicles running higher energy demands from fuel pumps, ignition systems and aftermarket electronics.
