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 improv 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 20% greater flow when compared to stock. With these flow and efficiency improvements also comes greater power, particularly off the line, culminating in maximum gains of +7 WHP & +12 lb-ft at 2500 RPM on a completely stock vehicle.
Like its smaller bodied 'G' chassis siblings, the Dinan carbon fiber intake for the bigger B58 vehicles utilizes a semi-open design that incorporates multiple auditory ports on a revised lid, so induction sounds of the turbo are more evident. Beyond the additional sound openings employed in the new design, the immense resonator assembly used in the stock setup to reduce unwanted turbo sounds is also 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.
Have you been longingly looking at the 2/3/4 series and become jealous of all the aftermarket options available to them? Have you reached out and pled with your favorite manufacturer to produce solutions to bigger bodied platforms so you too can enjoy added performance and sound? Have you thought all of it was in vain and your requests were ignored? That is not the case. Dinan has heard your inquiries and is pleased to offer an intake for the B58 powered 'G' chassis cars of the 5/6/7/8 and X series.
X3/X4 M40i FITMENT: D760-0068 is ONLY compatible with the 2018-2019 model years for the X3 & X4 M40i. In 2020 the air box changed to a different configuration which affects fitment of the Dinan intake. INLET NOTICE: For B58 'G' chassis 5/6/7/8/X owners that wish to run the Dinan Turbo Inlet (D760-0061) for maximum sound, the appropriate Dinan Intake (D760-0068) as well as the associated Inlet Fit Kit (D763-0100) are REQUIRED. The Dinan Turbo Inlet will NOT mate with the factory intake system.
