The CTS Turbo crank pulley is lightened to reduce parasitic drag on the engine.
This results in faster revving and more horsepower. Included in the kit is the lightened crank pulley, replacement OEM bolt and a shorter belt.
The pulley is made from T6 6061 aircraft grade aluminum and hard anodized to reduce wear. Gains of 5-7 horsepower can be expected.
This kit fits all MQB models: MK7 GTI, MK7 GOLF R, Audi A3 and Audi S3
NOTE: VW TOOL T10355 IS REQUIRED FOR INSTALLATION
