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.. The semi-open design has been meticulously engineered to deliver improved flow as well as a pronounced sporty sound through the incorporation of multiple ‘sound’ ports in the revised air box lid so induction sounds of the turbo are more evident. Beyond the additional sound openings employed, the immense resonator assembly used in the stock setup to reduce unwanted turbo sounds has also been eliminated with the Dinan system. Together, these elements allow the engine to nearly achieve its full sound potential, but when paired with the optional turbo inlet (and fit kit) the full intake tract to the turbo is effectively replaced for further audio enhancement.. NOTE: 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.. 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.. X3/X4 M40i FITMENT: D760-0075 is ONLY compatible with the 2020-2025 model years. Pre-LCI (2018-2019) models utilized a different configuration which affects fitment of the Dinan intake.. With the Dinan LCI M40i intake you will be sure to hear, and feel, the thrill of improved throttle and turbo response, ensuring a more dynamic driving experience!.
