Dinan Cold Air Intake for 2020-2026 BMW M240i & M340i - D760-0052

Fits 2020-2026 BMW M340i and 2022-2026 BMW M240i (Base & xDrive) without factory bracing.

The Dinan Cold Air Intake (D760-0052) is engineered to maximize airflow by utilizing the maximum available volume within the engine bay. Unlike basic intake upgrades that only replace the lid, Dinan reworks the entire lower air box to achieve a 60% increase in volume over stock. This expanded housing contains a custom, free-flowing filter with 115 in² of surface area—a 40% increase over the factory 82 in² unit.

To maintain consistent performance without heat soak, Dinan integrated a secondary inlet featuring patterned openings positioned away from the engine. This design provides additional air volume to the turbocharger while ensuring intake temperatures remain low during aggressive driving or multiple gear pulls. The result is a dyno-verified increase of up to 9 WHP and 8 lb-ft of torque at 6500 RPM on a stock vehicle, paired with improved throttle response and a sportier induction sound.
