Dinan BMW M240i/M340i/M440i G Series Black Air Intake

PLEASE NOTE: THESE WILL ONLY FIT MODELS UP TO THE YEAR 2025, THEY WILL NOT FIT 2026 MODELS. The M240i/M340i/M440i boast impressive performance and style, but their stock intake system falls short, featuring an airbox and intake resonator that produce uninspiring sounds. Dinan’s intake system corrects this with a semi-open design that flows 58% more air, boosting top-end power, throttle response, and sound. To achieve these gains, the lower airbox has been enlarged to accommodate a 40% larger custom filter. Extensive testing led to the addition of secondary inlets, strategically placed to increase airflow without raising turbo inlet temperatures. The result is improved throttle response, +9 WHP / +8 ft-lbs torque, and enhanced turbo and BOV sounds. With a Sleek Black finish, the Dinan intake not only performs but also elevates the engine bay’s aesthetics, making it a perfect upgrade for an already impressive platform. Features: More Power: Max gains of 9 WHP and 8 lb-ft of torque @ 6500 RPM on a completely stock vehicle. Enjoyably louder, sportier sound. Improved throttle response Outflows factory intake by 58% or more. Larger volume air box (60% larger than stock). 40% increase in filter area (stock: 82 in², Dinan: 115 in²) for optimum flow. Compatible with all G2x Mx40i's with and without factory bracing. Quick and easy installation
