Dinan Carbon Fiber Cold Air Intake BMW M240i/M340i/M440i G20/G23/G26/G42

OVERVIEW

The M240i, M340i, and M440i are impressive cars in terms of performance and style — but you'd never know it looking at the stock intake system, swaddled by seemingly unfinished strut braces. In stock trim, they come with a dry, lifeless airbox housing a basic panel filter, plus an intake resonator whose sole job is eliminating the turbo/intake noises enthusiasts actually want to hear. The Dinan Carbon Fiber Cold Air Intake rights these wrongs with a semi-open design capable of flowing 58% more air than stock, resulting in additional top-end power and sharper throttle response — all while remaining fully compatible with factory strut bracing. To achieve those gains, the entire lower airbox has been reworked and enlarged by 60%, housing a 40% larger custom filter. Strategically patterned secondary air inlets let you hear the turbo spool and BOV without raising intake temps, while the exposed carbon fiber construction transforms the engine bay's look from drab and utilitarian to genuinely show-worthy.
