Dinan Semi-Open Intake for BMW M240i / 340i / 440i 2016-2021
Note:
The Dinan Semi-Open Carbon Fiber Cold Air Intake for B58 Engines in F2x/F3x vehicles merges the exceptional performance of the closed intake system with enhanced turbo sounds for those seeking a more audible driving experience. This semi-open intake features a revised lid with an additional auditory port, allowing the turbo’s signature sounds to be more prominent without compromising the power gains or the intake’s visually striking carbon fiber build. For even more sound and performance, the intake can be paired with the optional turbo inlet, creating a completely redesigned intake path to the turbo.

-
Enhanced Sound: Semi-open design with a revised lid for increased turbo sound.
-
Improved Throttle Response: Larger airbox and filter improve airflow, reducing strain on the turbo.
