Dinan Carbon Fiber Cold Air Intake for BMW G20 M340i and G42 M240i

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.

The entire lower box of the intake system has been reengineered and enlarged to maximize airflow within the engine bay, allowing for a 40% larger, custom, free-flowing filter to be housed inside. This increased filter surface area and improved airflow path result in higher horsepower and torque, with peak gains of up to 9 wheel horsepower and 8 lb-ft of torque at 6500 RPM on a stock vehicle. The larger volume air box, which is 60% bigger than the stock version, outperforms the factory intake by over 58%, providing a noticeable improvement in throttle response and overall engine performance. The intake features a sleek carbon fiber construction, adding both durability and aesthetic appeal to your engine bay. Designed specifically for the BMW G20 M340i and G42 M240i models without factory bracing, this intake is a straightforward upgrade that combines maximum flow with ease of installation. A secondary open-air inlet was carefully tested and optimized to balance increased volume with temperature control, preventing any rise in turbo inlet temperatures during demanding driving conditions. This thoughtful design ensures reliable performance whether you're doing high-speed runs or spirited pulls, maintaining consistent intake temperatures even under intense stress. The Dinan Cold Air Intake provides an enjoyably louder, sportier exhaust note, enhancing the driving experience without compromising reliability. Installation is quick and straightforward, making it accessible for enthusiasts and professionals alike. Please note that this intake is not compatible with factory or aftermarket braces, but retrofit kits are available for owners of non-brace compatible systems who wish to add braces later. This product is not CARB approved but is designed to meet high-performance standards, and Dinan recommends ensuring proper installation and handling. Upgrade your BMW today with this premium intake for improved power, sound, and engine response, all wrapped in a sleek carbon fiber finish that complements your vehicle’s aesthetic.
