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