For your Audi RS5, this used OEM secondary air pump check valve (8K0131351B) is designed for the 4.2L V8 (4163cc) engine. Also called a secondary air injection check valve, it prevents hot exhaust gases from flowing back into the air pump during the cold-start cycle. A failing valve often triggers a check engine light or causes the secondary air system to malfunction, leading to failed emissions tests.
