This is a 1.5mm oversize Inconel exhaust valve for four-valve Volkswagen and Audi engines, including 16v, 20v and early 32v units. The valve head and stem are back cut to improve flow, and 034Motorsport reports gains of up to 20 cfm simply by fitting them to an otherwise stock head. Because of the oversize head, the valves need upgraded larger valve seats, and they work with OE-fit springs, retainers, guides and clips. Valves are sold individually.
