Audi B7 A4 2.0T ECS Lightweight Crank Pulley Kit
Take back your horsepower. Accessories like A/C, power steering, and the alternator eat great gobs of horsepower. Cut those losses with an underdrive pulley from ECS Tuning.
Our low mass underdrive pulleys are precision machined from lightweight aluminum to spool up faster, while spinning accessories at a slower speed to save power losses.
Available in a black finish , these kits contain pulley and new correct-sized accessory belts; a packaged performance tweak that looks great.
