This sealed carbon fibre intake system delivers proven airflow gains, cooler charge air, sharper throttle response and stunning under‑bonnet aesthetics. If you want the best BMW M5 cold air intake, the Dinan carbon fibre intake is the benchmark.
Engineered specifically for the F90 M5, the system replaces the factory airboxes with enlarged, fully sealed carbon fibre airboxes and a functional centre wishbone inlet that draws additional ambient air from a scoop behind the front grilles. The gloss UV‑coated 2x2 carbon weave spans the entire engine bay, improving heat deflection and resisting heat soak while transforming the look of your M5 with genuine motorsport presence.
