Dinan 22-26 BMW M240i (G42)/20-26 BMW M340i (G20) 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/G42 D760-0052 is not compatible with factory or aftermarket braces. 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 (D760-0058) 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.

• 40% increase in filter area (stock: 82 in², Dinan: 115 in²) for optimum flow.
• Compatible with the G20 M340i's & G42 M240i's 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

Upgrade your BMW with the Dinan Carbon Fiber Cold Air Intake, designed specifically for the G20 M340i and G42 M240i models. This high-performance intake system features a larger, 60% increased airbox volume and a 40% larger filter surface area compared to stock, significantly enhancing airflow for improved engine efficiency. The reworked lower box maximizes available space within the engine bay, allowing for a custom, high-flow filter that boosts power and torque.
The intake system has been engineered with a secondary inlet featuring patterned openings that effectively balance increased volume with minimal impact on inlet air temperatures, ensuring consistent performance even during demanding driving conditions. This design maintains the optimal intake temperature, preventing heat soak from the engine bay, which is critical for maintaining power gains.
Installation is straightforward, making it accessible for enthusiasts seeking a sporty upgrade without extensive modifications. The system outperforms the factory intake by over 58%, delivering a noticeable increase in throttle response and a more aggressive exhaust note. This intake is compatible with the G20 M340i and G42 M240i models without factory bracing, providing a seamless fit and reliable operation.
Crafted from durable carbon fiber, this intake not only enhances airflow but also adds a sleek, high-tech aesthetic to your engine bay. For owners with existing non-brace compatible Dinan intakes, a retrofit kit is available to enable the use of braces without purchasing a new intake. This kit includes a lid and hardware, ensuring your system remains up-to-date and optimized for performance.
Designed for enthusiasts who demand maximum performance, the Dinan Carbon Fiber Cold Air Intake is a proven upgrade that combines increased horsepower, improved throttle response, and a sportier sound, elevating your driving experience to the next level.
