Dinan Cold Air Intake – BMW M240i (G42) M340i/M440i (G20/G22/G23/G26) – Carbon Fibre

Dinan is one of the most respected names in BMW performance, and this carbon fibre cold air intake is a straightforward way to unlock more from your B58-powered BMW. It replaces the restrictive factory airbox with a semi-open design that flows significantly better, lowers intake air temperatures, and sharpens throttle response — all in around an hour of installation time.
