Dinan Closed Cold Air Intake for BMW M240i / 340i / 440i 2016-2021
Note:
The Dinan Carbon Fiber Cold Air Intake for the B58 Engine takes the high standards set by its N55 predecessor to new levels of performance and refinement. Designed with a focus on maximizing airflow efficiency, the intake improves throttle response and reduces turbocharger strain by integrating a larger airbox and an optimized carbon fiber intake tube, which eliminates turbulence-inducing features found in the factory setup. By removing the stock intake's sound-dampening baffles and Helmholtz chamber, Dinan enhances airflow and provides a natural, sportier intake sound.
This B58 intake features a full carbon fiber construction, ensuring both lightweight durability and premium appearance, while a high-quality coating preserves its aesthetic and performance integrity. The result is a system that not only enhances power but also elevates the engine bay's appearance, making it an ideal choice for performance enthusiasts.
Key Features:
-
Power Gains: +15 HP and +13 lb-ft at 6000 RPM on stock setup (13 WHP and 11 WTQ).
-
Improved Sound: Sportier intake tone by removing sound-dampening elements.
-
Sealed Cold-Air System: 30% larger airbox for superior insulation against heat.
-

-
Enhanced Air Mass Meter Housing: Injection-molded and 8% larger than stock.
-
CARB Compliant: 50-state emissions legal (CARB EO D-176-56 for select models).
