Dinan Cold Air Intake - 2020-2026 BMW M340i

The M240i & M340i are impressive vehicles in terms of performance and style but that is not conveyed when viewing its lackluster stock intake system. In stock trim, the M240i/M340i comes with a dry and lifeless air box housing a basic panel filter that is also accompanied by an intake resonator whose job it is to eliminate turbo/intake noises. The same noises that those in the performance world relish. Essentially BMW has seen fit to give M340i owners an air box that looks uninspiring, flows adequately but not ideally, and emits no noise. The exact opposite of what the platform exudes otherwise. The Dinan carbon fiber intake for the platform rights these wrongs and delivers a semi-open intake capable of flowing 58% more air than the stock system resulting in additional top end power and increased throttle response. At the same time revealing a more aggressive, sporty carbon fiber appearance, and an increase in sound courtesy of the removal of the intake resonator and implementation of a semi-open design.
