BMW M240i Turbo Inlet Pipes - Dinan - Dinan - Carbon Fiber - `16-`21. A direct-replacement carbon fiber inlet for the B58-powered M240i that improves airflow, sound, and durability while maintaining factory fitment.

Replacing the failure-prone plastic OEM piece, Dinan’s inlet uses robust carbon fiber and CNC-machined fittings for precise, reliable installation. The pipe’s enlarged, optimized path removes restrictions and deletes the factory sound resonator, reducing turbulence and letting the turbo ingest air more efficiently. The result is a crisper response under throttle with a fuller induction soundtrack, all without compromising OEM mounting points or serviceability.

• Up to 24% greater overall volume; ~10.8% larger average I.D.
