Agency Power Lightweight Under-Drive Crank Pulley Volkswagen Golf GTi | Audi A3/S3


Agency Power

Model #AP-MK7-130

The Volkswagen 1.8L / 2.0L TSI engine is shared across a variety of line which includes Golf, GTi, and even the Audi A3/S3 along with the Audi TT. A simple and popular modification to the TSI engine is adding the Agency Power Lightweight Under-Drive Crank Pulley that gives your VW a quicker throttle response as well as more horsepower and torque. This is due to the pulley decreasing the rotating mass which results in improved performance, quicker reving and even a gain in fuel mileage. The pulley is smaller in diameter than stock and made from billet 6061 aluminum with a 304 stainless steel ring to prevent pulley wear against the oil seal. Cut precisely to spec on our CNC lathe and then CNC mill, the pair of pulleys is anodized in black and laser engraved with the Agency Power text.  Each pulley kit includes a new shorter belt and factory bolt for a direct and hassle free installation.
