Dinan 20-26 BMW M240i/M340i/M440i (G20/G22/G23/G26/G42) Carbon Fiber Cold Air Intake

In order to achieve the gains in flow that set the Dinan intake system apart, the entire lower box of the system, and not just the lid, has been reworked and enlarged in an effort to make use of as much of the available real estate as possible within the engine bay. In turn, this allows a 40% larger, custom, free flowing filter to be housed within and maximum flow to be realized. However, a secondary inlet has always been desired by Dinan in order to effectively fill the volume of the enlarged air box and increased filter surface area. This desire led to a multitude of experiments being conducted on the effectiveness of a possible open-air inlet in the system. With different shapes, locations, and sizes of openings being tested, the goal was to ensure that the added secondary inlet did not cause any unwarranted side effects such as an increase in air temps in the system. This is commonplace with open-air intake systems where overheated engine bay air is employed in the intake tract. The results of these tests showed that the patterned openings present in the final iteration of the box located on the opposite side from the engine provided a perfect balance of additional volume to assist the factory inlet all the while not causing an increase in turbo inlet temperatures. This was the case regardless of testing conditions (single/multiple gear pulls, constant speed, 0-100mph runs, etc.). Carbon Fiber - G20/G22/G23/G26/G42 For those who already own a non-brace compatible Dinan intake (D760-0052) but now want to run braces without purchasing a completely new intake kit you can order the retrofit kit (lid and hardware) seperately for $84.95. To do so contact the tech sales department at 1-800-341-5480 and request part number D763-0185.

• More Power: Max gains of 9 WHP and 8 lb-ft of torque @ 6500 RPM on a completely stock vehicle.
• 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.
• Larger volume air box (60% larger than stock).
• Outflows factory intake by 58% or more.
• Enjoyably louder, sportier sound.
• Quick and easy installation
• Improved throttle response

The Dinan Carbon Fiber Cold Air Intake for BMW models including G20, G22, G23, G26, and G42 is engineered to optimize airflow and boost engine performance. Featuring a reworked and enlarged lower box, this intake system maximizes available space within the engine bay to house a 40% larger, custom, free-flowing filter. This increased filter surface area enhances airflow, resulting in improved throttle response and power gains.

The intake system incorporates a secondary inlet with patterned openings, carefully tested to balance increased volume with minimal impact on intake air temperatures. Extensive testing ensured that this open-air inlet does not cause detrimental heat soak, maintaining optimal intake conditions during various driving conditions, including high-speed runs and aggressive pulls. The result is a consistent increase in airflow, outpacing the factory intake by over 58%, with gains of up to 9 wheel horsepower and 8 lb-ft of torque at approximately 6,500 RPM on stock vehicles.

Constructed from high-quality carbon fiber, this intake not only improves performance but adds a sporty aesthetic to your engine bay. The system is designed for quick and straightforward installation, making it accessible for most enthusiasts. Additionally, it provides a more aggressive, sportier sound, enhancing the driving experience without compromising reliability. The intake is compatible with all G2x M40i models, with or without factory bracing, and fits a broad range of BMW models including the M340i, M440i, and M240i.

For owners of previous Dinan intake models, a retrofit kit is available to allow installation of braces without purchasing a new intake. This kit includes the lid and hardware, offering a cost-effective upgrade option. Overall, the Dinan Carbon Fiber Cold Air Intake is a performance-oriented upgrade that combines enhanced airflow, improved throttle response, and aesthetic appeal for BMW enthusiasts seeking maximum performance gains.
