Improve turbo efficiency, throttle response, and induction sound with the Dinan Carbon Fiber Turbo Inlet Pipe for BMW M240I/M340I/M440I.

Designed specifically for the BMW G42 M240i, BMW G20 M340i, BMW G21 M340i Touring, BMW G22 M440i Coupe, BMW G23 M440i Convertible and BMW G26 M440i Gran Coupe, this high-performance inlet pipe replaces the restrictive and failure-prone factory plastic turbo inlet with a stronger, smoother flowing carbon fiber alternative.

The factory inlet includes resonators and design compromises that reduce airflow efficiency and mute turbo sound. Dinan removes these restrictions with a larger, optimised flow path that provides a more uniform air stream to the turbocharger.

The result is faster turbo spool, sharper throttle response, improved turbo efficiency, and a more pronounced induction soundtrack that lets you hear the turbo working as it should.

Featuring 14% greater internal volume and an average 7.7% larger internal diameter than OEM, the Dinan turbo inlet maximises available airflow while maintaining perfect OEM-style fitment through precision CNC-machined connections.

Constructed from premium carbon fiber, it also adds durability and a refined performance look to the engine bay.

Installation is quick, direct, and fully bolt-on.
