034Motorsport High Flow Valve Pair, Audi I5 20V, .5mm Oversize, Stainless Intake, Inconel Exhaust
These high-flow valves for the Audi I5 20V are sold as a pair, with stainless steel used for the intake valve and Inconel for the exhaust valve, each 0.5mm larger than stock. The valves are back cut and swirl polished for better flow, and 034Motorsport reports gains of 15cfm or more without any porting. They work with OE-fit springs, retainers, guides and clips, but the factory seats must be cut to the larger diameter. Otherwise they are a direct fit for the stock head.
