Dinan Semi-Open Intake – BMW M240i/M340i/M440i (F22/F23/F30/F32/F33/F34/F36) – Carbon Fibre

Dinan has been extracting performance from BMW engines for decades, and this semi-open carbon fibre intake is a prime example of their engineering approach — more airflow, real power gains, and a fitment designed to work straight out of the box. Built for the BMW B58 platform, this intake replaces the restrictive factory airbox with a free-flowing design that lets the engine breathe properly under hard use.

This listing covers the Dinan Semi-Open Intake (D760-0046-A) for 2016–2021 BMW M240i, M340i, and M440i models across the F22, F23, F30, F32, F33, F34, and F36 chassis platforms.
