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
