Dinan 19-26 BMW Z4 sDrive30i Cold Air Intake

To achieve the gains in flow that the Dinan intake delivers, 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 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 incorporated enlarged and optimized Dinan 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.). Semi-Open - Carbon Fiber - A90/G29

• Lid includes a brace valley to accommodate factory braces or optional Dinan strut braces
• More Power: Max gains of 6 WHP and 7 lb-ft of torque on a completely stock vehicle
• 40% increase in filter area (stock: 82 in², Dinan: 115 in²) for optimum flow
• Extended intake pipe inclusive of the turbo inlet
• Larger volume air box (60% larger than stock)
• Enjoyably louder, sportier sound
• Outflows factory intake by ~15%
• Quick and easy installation
• Improved throttle response

Upgrade the intake system on your BMW Z4 sDrive30i or Toyota GR Supra with the Dinan D760-0066 Semi-Open Carbon Fiber Cold Air Intake. Designed for the A90 and G29 platforms, this system replaces the factory lower air box and intake components with a larger-volume design engineered to improve airflow, throttle response, and induction sound. The reworked air box uses available engine-bay space more effectively while maintaining compatibility with factory braces or optional Dinan strut braces through an integrated brace valley in the lid.
The enlarged air box houses a custom free-flowing filter with 40% more surface area than the factory filter, helping support increased airflow through the intake tract. A strategically patterned secondary inlet on the side opposite the engine increases air-box volume without drawing excessive heat from the engine bay. Dinan testing showed that the semi-open design helps maintain turbo inlet temperatures across various driving conditions while supporting the optimized primary inlet. The included extended intake pipe also incorporates the turbo inlet for a comprehensive airflow upgrade.
On a completely stock vehicle, the Dinan D760-0066 can deliver maximum gains of up to 6 wheel horsepower and 7 lb-ft of torque. The intake outflows the factory system by approximately 15% and produces a louder, sportier induction note under acceleration. Its direct-fit design allows for quick and straightforward installation using common hand tools, making it a practical performance enhancement for daily driving, spirited use, and track applications. This product is not CARB approved and may not be legal for use on pollution-controlled vehicles in certain jurisdictions.
The Dinan D760-0066 fits the 2019–2024 BMW Z4 sDrive30i and 2021–2024 Toyota GR Supra applications listed by the manufacturer. Verify vehicle compatibility before ordering, and review local emissions regulations before installation.
