Dinan 25-27 BMW M340i/M440i (G20/G21/G22/G23/G26) Gen3 B58 Carbon Fiber Turbo Inlet Pipe

Regardless of application, a Dinan turbo inlet replaces the weak, and failure prone, plastic factory inlet with a more robust carbon fiber one. OEM + fittings are utilized to ensure proper fitment and guarantee installation as a direct replacement to the OEM inlet. Beyond material and fitment however are the improvements to the characteristics of the primary element in the system, the pipe itself. The stock turbo inlet has incorporated additional features (multiple in some cases) that introduce flow restrictions and turbulence while also reducing turbo noises. All of which are unwanted but easily rectified by removing the various resonators and enlarging (and optimizing) the path for a more uniform flow. The result is an inlet that delivers not only more air and allows the turbo to be more efficient (work less) but also provides the oft desired amplification to the turbo induction soundtrack. Carbon Fiber - Gen 3 M340i M440i For best sound and flow charectaristics it is best to run the appropriate Dinan air intake element.

• Increased turbo efficiency and reliability courtesy of maximum unimpeded and uniform airflow.
• Carbon fiber construction for increased durability and visual appeal.
• Eliminates the factory sound resonator for increased turbo sounds.
• Increase in overall intake volume and flow rate over OEM inlet.
• Direct replacement of plastic OEM turbo inlet.
• Quick and easy bolt-on installation.

Upgrade the induction system of your 2025-2027 BMW M340i or M440i with the Dinan D760-0079 Gen 3 B58 Carbon Fiber Turbo Inlet Pipe. Designed as a direct replacement for the restrictive factory plastic inlet, this component uses durable carbon fiber construction and OEM-style fittings to provide a precise fit and straightforward installation. It is engineered for select BMW G20, G21, G22, G23, and G26 chassis equipped with the Gen 3 B58 engine.
The factory turbo inlet incorporates resonators and other internal features that can disrupt airflow, introduce turbulence, and reduce turbocharger sound. The Dinan inlet removes these restrictions while enlarging and optimizing the airflow path for a smoother, more uniform supply of air to the turbocharger. Improved airflow can help the turbo operate more efficiently while supporting increased intake volume and flow compared with the OEM inlet. Removing the factory sound resonator also produces a more pronounced turbo induction sound for drivers who want greater auditory feedback from the engine bay.
Built for dependable performance and long-term durability, the Dinan D760-0079 combines functional airflow improvements with a clean carbon fiber appearance. For the best sound and flow characteristics, Dinan recommends pairing this turbo inlet with the appropriate Dinan air intake element. Installation is designed as a quick, direct bolt-on replacement using the factory mounting locations and compatible fittings, making it a practical upgrade for street-driven and performance-focused BMW applications.
