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
