ECS Tuning lightweight pulleys help improve throttle response. This replacement for the weighted factory pulley is easy to install and comes in at a very light .71lbs - 78% lighter than the stock 3.25lbs. This reduction in rotational inertia allows the engine to rev faster and more freely, resulting in a car that is more enjoyable to drive, with a sportier feel. Featuring a black anodized finish, this pulley reuses the stock belt. No modifications required. An excellent first modification or an equally good addition to an already modified Volkswagen.
