PROFILE

The ARM N55 Intake is a complete induction solution for the N55 found in the E9X chassis!  From the turbo to the air filter the entire system has be redesigned to improve airflow and turbo spool, resulting in more power and better throttle response for your N55 powered BMW.  The ARM N55 Intake shortens the induction pathway from the OEM setup by 68%.  By moving the air filter to behind the headlight area, the path of airflow from the high-flow performance filter to the turbo is greatly improved. 

N55 Intake

 

To make this happen we completely redesigned the N55 turbo inlet.  The ARM N55 Inlet inserts into the OEM turbo with factory-like precision.  It then rapidly expands to 3" and this size is maintained throughout the rest of the intake all the way to the high-flow air filter.  While the OEM N55 inlet reduces to 46mm before the turbo inlet, the ARM N55 Inlet measures in at 75mm, a 63% increase over OEM. 

N55 Intake Inlet



The ARM N55 Intake utilizes the largest possible air filter for the location behind the passenger side headlight.  This air filter measures a full 124 cubic inches of filter surface area, in an oval design to allow it to fit in-between the headlight housing and coolant expansion tank.

N55 Intake



At the center of the ARM N55 Intake is the primary intake runner pipe which has several important design features.  Firstly, it is where the MAF sensor is relocated, utilizing a CNC machined MAF flange which provides a secure seal between the two components.  Secondly, the ARM N55 Intake includes a PCV port on the intake tube to reconnect the PCV line.  This allows for proper function of the OEM PCV system.   Lastly, the ARM N55 Intake is designed with an open-ended bracket to keep the filter stable and secure during aggressive driving.  

N55 Intake



In order to relocate the filter to the front of the headlight we have included a MAF extension harness so there is no cutting or splicing of wires.  This harness simply clips into the original harness near the back of the engine and extends all the way to the new position for the MAF sensor on the precision machined ARM N55 MAF housing on the intake pipe.

*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.
