OVERVIEW
The BMS Dual Cone Intake (DCI) swaps the restrictive factory N54 airbox for a pair of free-flowing inverted cone filters, one feeding each turbo. The result is a noticeable bump in power on an otherwise stock car, sharper throttle response and far more audible turbo and induction sound.
The kit bolts to the factory turbo inlets using powder-coated aluminum tubes and anodized couplers, so there is no cutting or drilling and the car can be returned to stock. It is made in the USA and carries a CARB Executive Order (D-744-2) for 2007–2012 N54 applications.
