The Dinan D760-0058 Carbon Fiber Cold Air Intake replaces the restrictive factory air box on the BMW M240i, M340i, and M440i platforms with a semi-open, high-flow carbon fiber system designed for maximum performance and sound. The re-engineered lower box increases volume by 60% and houses a custom filter with 40% more surface area. A secondary inlet design was carefully developed to improve airflow without heat soak, delivering dyno-proven gains of +9 WHP and +8 lb-ft of torque on stock vehicles. The result is enhanced throttle response, a noticeably more aggressive induction note, and a dramatic under-hood visual upgrade.
