Compatible with 2019-2022 BMW® 230I/330I/430I/Z4 30I G20/G22/G23/G26/G29/G42. This product is not created or sold by BMW®.; Turbo inlet pipes serve two very distinct, and differing, purposes. On one hand the optimization of a turbo inlet pipe will encourage better turbo efficiency and responsiveness by allowing the turbo to ingest more air by way of an unobstructed and larger volume flow path. On the other, you have a more visceral benefit that some may argue is equally, or even more, important than that of efficiency/flow optimization --- increased sound. No matter which of the distinct purposes is favored, Dinan will deliver on both.
