Complete kits follow the seven-digit catalogue format, three digits for the application then four for the kit, for instance 204-4706 or 251-4703. Individual spares use a different, letter-based code for a nut, a washer or a short bolt: they let you top up a part-used kit without buying another. Both generic kits and kits aimed at a specific engine are listed, BMW M40 and M42 or the VAG 1.8 T 20V AEB.
