Dinan 20-25 BMW X3/X4 M40i Cold Air Intake

While sound is undoubtedly important for a large swath of consumers, performance enhancements are equally as important to others. Common to all Dinan intake design, improvements upon the factory design by increasing flow via a larger airbox and filter element were made. These standard adjustments improve throttle response (and acceleration) and lessen the strain on the turbocharger for maximum efficiency. While box and filter enlargement and redesign are major factors in ultimately producing a more potent intake, they are not the only variables in creating a more efficient design either. The resonator assembly that limited auditory enjoyment also created a more turbulent airflow path by introducing alternative stunted pathways. The Dinan carbon fiber intake tube eliminates these flow disruptions with a smoother, direct flow path for maximum potential efficiency and an overall 7% increase in flow when compared to stock. Carbon Fiber - G01/G02 For LCI X3/X4 M40i owners that wish to pair the Dinan Turbo Inlet (D760-0062) to the Dinan intake (D760-0075) for maximum sound, the associated Inlet Fit Kit (D763-0101) is REQUIRED. The Dinan Turbo Inlet will NOT mate to the Dinan, or factory, intake system without the fit kit.

• Improved throttle/turbo response compared to stock resulting in quicker acceleration
• 66% larger volume air box (stock: 150in3, Dinan: 250in3) for increased breathability
• Flows 7% more than stock (stock: 458 CFM, Dinan: 589 CFM in 24-inches of H2O)
• 44% increase in filter area (stock: 57in², Dinan: 82in²) for optimum flow
• Washable and reusable high flow pleated cotton gauze filter
• A pronounced sporty sound courtesy of a semi-open design
• Optimized carbon fiber intake tube with less restriction
• Eliminates upper intake resonator
• Quick and easy installation

Upgrade the induction system on your BMW X3 or X4 M40i with the Dinan D760-0075 Cold Air Intake. Designed for G01 and G02 chassis models, this intake improves airflow over the factory system with a larger airbox, expanded filter area, and optimized carbon fiber intake tube. The smoother intake path reduces turbulence and restriction, helping improve throttle response, turbocharger efficiency, and acceleration while delivering a more pronounced sporty sound through its semi-open design.
The enlarged airbox provides 66% greater volume than stock, while the high-flow filter offers 44% more filter area to support improved engine breathing. The system flows up to 7% more than the factory intake under comparable test conditions. Its washable and reusable pleated cotton gauze filter provides long-term serviceability, while the carbon fiber tube eliminates the upper intake resonator and replaces its restrictive, indirect airflow path with a more direct design. Installation is quick and straightforward using factory mounting locations.
This Dinan intake fits 2020-2024 BMW X3 and X4 M40i applications. Owners of LCI X3/X4 M40i models who plan to combine this intake with the Dinan Turbo Inlet, part D760-0062, must also use the Dinan Inlet Fit Kit, part D763-0101. The fit kit is required because the Dinan Turbo Inlet will not mate directly with either the Dinan or factory intake system without it. This product is not CARB approved and may require acknowledgment of emissions-related restrictions before purchase or installation.
