Dinan PEX Cold Air Intake for BMW G20/G22/G23/G26 (2019-2022 3 Series and 4 Series Models) – Enhanced Performance and Flow

To accomplish the feat in flow that sets the Dinan intake system apart the entire lower box of the system, and not just the lid, has been reworked and enlarged 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 on the opposite side from the engine provided a perfect balance of additional volume to assist the factory snorkel 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.). PEX - G20/G22/G23/G26/G42

• 40% increase in filter area (stock: 82 in², Dinan: 115 in²) for optimum flow
• Compatible with all G2x/G4x x30i's with and without factory bracing
• High heat deflection PEX construction and an OEM look
• 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 PEX Cold Air Intake system offers a significant upgrade for BMW 3 Series and 4 Series models from 2019 to 2022, including G20, G22, G23, and G26 chassis. Designed with a focus on maximizing airflow and improving throttle response, this intake features a reworked and enlarged lower box that utilizes the available space within the engine bay. The custom, free-flowing filter is 40% larger than the stock component, providing increased filtration area and optimal airflow for enhanced engine performance. This larger filter surface allows for better air intake, supporting increased power output and a sportier engine sound. The PEX construction uses high heat deflection materials to maintain durability and an OEM look, ensuring a seamless integration with your vehicle's aesthetics.
The intake system's innovative design includes a secondary open-air inlet, carefully tested to balance additional volume with stable intake temperatures. Patterned openings in the air box facilitate extra airflow without raising turbo inlet temperatures, even during high-demand driving conditions such as spirited pulls or high-speed runs. This thoughtful engineering results in a cooler, more consistent air supply, which translates into improved throttle response and overall engine efficiency.
bsp;Installation is straightforward, making this upgrade accessible for DIY enthusiasts and professional installers alike. The system outperforms the factory intake by over 58%, delivering a more aggressive and louder intake tone that enhances the driving experience. Whether you're looking for improved performance, a sportier sound, or both, the Dinan PEX Cold Air Intake provides a reliable and high-quality solution that complements the engineering of your BMW. Elevate your driving dynamics with this high-performance intake designed specifically for your vehicle's engine bay and airflow requirements.
