Neuspeed Power Pulley Kit / B7 Audi A4 2.0T FSiYour car's power steering pump, alternator and A C are powered by a belt connected back to the crankshaft pulley. Spinning these pulleys draws precious horsepower from your engine. NEUSPEED's powertrain engineer, using sophisticated CAD software, performed a mass properties analysis of the crank pulley. The result is reduced parasitic drag on the engine and increased horsepower. This kit includes a new under drive crankshaft pulley and shorter belt.
