DINAN – Carbon Fibre Cold Air Intake – BMW 230i / 330i / 430i (19–24)

DINAN – Carbon Fibre Cold Air Intake – BMW 230i / 330i / 430i (19–24)

Transform the personality of your BMW x30i with the Dinan Carbon Fibre Cold Air Intake, engineered to inject character, performance, and style back into the refined B48-powered G-series platform. Replacing the restrictive and muted factory airbox, this semi-open carbon intake flows 58% more air than stock, dramatically improving throttle response, airflow capacity, and turbo acoustics.

The redesigned lower airbox is 60% larger than factory and houses a custom high-flow filter (40% larger surface area) to maximise volume and ensure unrestricted breathing—even for high-powered builds with upgraded turbos and fueling systems. Dinan’s engineers performed extensive testing to develop a secondary open-air inlet that increases flow without raising intake temperatures, balancing efficiency and reliability under demanding track or street conditions.

Crafted from premium 2x2 gloss twill carbon fiber, the intake not only performs but adds a striking visual upgrade to the engine bay. With its enhanced sound profile and OEM+ fitment, it delivers the perfect blend of function, form, and attitude expected from Dinan.
