PROFILE
The ARM Motorsports N54 Inlets are the ultimate relocated inlet system for your N54. Relocating the inlets on your N54 with the ARM Inlets increase the power and torque of your N54 up to 60whp/60wtq. Expect improved turbo spool, faster peak boost, and more volume from the turbochargers on your N54. If you're looking to max out your stock or upgraded twin turbochargers these are a must!
The stock N54 inlets are narrow and flat, greatly restricting airflow to the turbochargers and handicapping their ability to spool quickly and hit target boost. The stock inlets connect from turbos on the passenger side of the engine to the airbox or upgraded intake on the driver-side, essentially "hugging" the engine. The stock inlet for the rear turbo wraps behind the engine while the stock front inlet wraps around the front of the engine where they come to meet on the driver-side and connect to either the stock airbox or upgraded intake, whichever you have your N54 equipped with.
CONSTRUCTION
The ARM N54 Relocated Inlets are constructed of high-temperature steel-reinforced silicone and move the intake filters for the turbochargers from the driver-side of the engine over to the passenger-side, reducing the length the intake air needs to travel significantly.
In addition, the ARM Inlets come with an air filter heat shield which assists in keeping the cooler air near the filters separate from hotter air coming from the engine adjacent to it.

The air filters on the ARM Inlets are secured in place with a filter bracket which prevents filters and inlets themselves from bouncing around during acceleration, braking, and cornering. Also included with the ARM Inlets is a support bracket for the boost solenoids. This keeps them locked into place during extreme driving.
To help make installation easy, relocation brackets for the coolant reservoir and power steering pump reservoir are included with the ARM Inlets.
