Description
Unlock hidden power and improve engine response with the Neuspeed Power Pulley Kit for the Audi A4 B7 2.0L TFSI. This performance upgrade is engineered to reduce parasitic drag on your engine accessories—such as the alternator, power steering pump, and A/C compressor—by replacing the factory crankshaft pulley with a lightweight, underdrive version.
Through advanced CAD-based mass properties analysis, NEUSPEED’s powertrain engineers optimized the design of the crank pulley to reduce rotational mass while maintaining ideal belt geometry. The result is a gain of 5 to 7 horsepower at the wheels, improved throttle response, and enhanced engine efficiency—all without compromising accessory functionality.
The crank pulley is CNC-machined from aerospace-grade 6061-T6 aluminum, then hard anodized for exceptional wear resistance. Unlike standard color anodizing, hard anodizing forms a dense, protective layer that stands up to heat and friction over long-term use.
This kit includes the underdrive crankshaft pulley and a shorter accessory belt for proper fitment. It’s a direct bolt-on solution designed specifically for the Audi A4 B7 platform, proudly engineered in Camarillo, California and manufactured in the USA.
