DINAN Cold Air Intake - BMW 230i/330i (19-24)

Enhance the sound, power, and visual appeal of your B48-powered BMW with the Dinan Carbon Fibre Cold Air Intake. The stock intake design, though functional, limits airflow and suppresses the turbo’s natural sound. Dinan’s re-engineered system corrects these shortcomings with a semi-open carbon fibre intake that delivers 58% more airflowthan stock, dramatically improving throttle response and under-hood aesthetics.

The lower airbox has been completely redesigned and enlarged (60% larger than stock) to maximize available space within the engine bay. It houses a custom free-flowing filter with 40% more surface area, ensuring the engine can breathe freely, especially for vehicles with upgraded turbos or fueling systems. Extensive testing led to the development of an optimized secondary air inlet, increasing airflow volume without raising intake temperatures — even under demanding driving conditions.

Crafted from premium 2x2 gloss twill carbon fibre, this intake is as stunning as it is functional. The semi-open design enhances induction sound, allowing drivers to enjoy pronounced turbo spool and blow-off acoustics — transforming the driving experience without compromising performance or reliability.
