This high-flow valve set is for Audi and Volkswagen 5-valve engines and uses 1.0 mm oversize intake and exhaust valves. The intake valves are high-temperature stainless and the exhaust valves are high-temperature Inconel, both with a high-flow profiled head and 6mm stems. It is a direct installation on all 20v and 30v 5-valve engines, although the stock seats need to be cut for the larger size. A valve seat change is not required, and the set covers one combustion chamber, so a 4-cylinder engine needs four sets.
