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!

n54 inlets

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.

One of the greatest challenges when upgrading to relocated inlets on your N54 is mitigating the heat of the air induced by the turbos.  With the inlets relocated to the passenger-side the filters are closer to the turbochargers where temperatures are hotter.  The ARM N54 Inlets come with a manifold heat shield which serves to help keep heat down near the turbos and away from the inlet filters.  It also assists with keeping heat away from the inlet tubes themselves. 

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.

ARM MOTORSPORTS LIFETIME WARRANTY

Every ARM Motorsports product is backed by a lifetime warranty which is automatically issued at the time of purchase. Your warranty protects you against any defects in craftsmanship or fitment. The warranty entitles you to a replacement unit.
*Kits are made-to-order. As we do not physically keep everything in stock, kits have a ship time of about 3 weeks after your payment has processed. This is common for the N54 Single Turbo market if you look on other websites.

Unleash the full potential of your N54 engine with our Top Mount Single Turbo Kit, engineered for seamless fitment, durability, and big power capability. Designed to support 800whp+, this kit is the ultimate upgrade for those who demand power without compromise.

High-Quality 304 Stainless Steel Manifold

Crafted from 304 stainless steel, the manifold offers superior heat resistance, corrosion protection, and structural integrity. Unlike lower-grade materials, 304 stainless ensures long-term reliability under extreme heat and boost pressures, making it ideal for high-performance applications. The precision-engineered tubular design is optimized for maximum exhaust flow, reducing backpressure and enhancing turbo efficiency. This manifold is similar to ones being sold on AliExpress and other overseas markets. However, we've partnered directly with the manufacturer to provide these manifolds in the highest of quality. Unlike those that are drop-shipping similar manifolds from unreliable sources. You are purchasing directly from the source.

Industry-Leading Fitment

Fitment has been meticulously tested and compared against all major top-mount kits on the market, and ours ranks among the best. The compact yet efficient design ensures hassle-free installation, eliminating clearance issues that plague other kits.

Smart Wastegate Placement

No more tearing the entire kit apart just to make a simple wastegate adjustment. Our strategically placed wastegate design allows for quick, easy access, so you can fine-tune your setup without unnecessary downtime.

Built for Serious Power

With the ability to support 800whp+, this kit is designed for enthusiasts pushing their N54 to the limit. Whether you’re chasing high-speed pulls or dominating the track, this setup provides the boost response, reliability, and power potential you need.
