The ARM Motorsports N54 Dual Cone Intake (DCI) allows you to easily add up to 20whp to your N54 335i by replacing the bulky OEM N54 intake with two open, high-flow dry media filters.  

HIGHLIGHTS

In addition, the design of the inner neck of the ARM air filters has been molded in a conical shape to further increase airflow by reducing resistance as air is being transferred from the filters to the aluminum adapters before finally entering the turbo inlets.

With less restriction, the N54’s turbos can draw in air more efficiently allowing faster turbo spool.  Power gains can be seen throughout most of the rpm range, but particularly above 5k rpm where full bolt-on N54’s can see as much as 20whp.  

In addition to the performance benefits, the ARM N54 Dual Cone Intake kit also opens up the sound of your turbochargers.  The OEM airbox is designed to decrease the sound of the N54’s turbos, but with the ARM DCI kit you can hear the sound of the turbos spooling up as they draw in air through the massive high-flow inverted filters.

FITMENT GUIDE

The ARM N54 Dual Cone Intake fits either the stock N54 turbo inlets and any upgraded inlets that fit the OEM airbox.
