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. 

HIGHLIGHTS

  • Gain up to 11whp
  • Precision Machined Turbo Inlet
  • Faster Turbo Spool
  • Increased Turbo Sound
  

 

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. 



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.



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.  



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.  



IN THE BOX

• ARM N55 Turbo Inlet Adapter
• ARM Intake Silicone Coupler
• ARM Intake Runner Pipe
• ARM High-Flow Air Filter
• ARM PCV Hose
• MAF Extension Harness
• Clamps

Simple Upgrade That Makes a Real Difference
Style: CF10140 Classic
Installed the Zezut cabin filter in my 2005 Infiniti G35 and noticed the difference immediately. The air inside the car felt fresher and cleaner right away — no more stale air circulating through the vents. The HEPA backing is a big deal, knowing it's actually filtering out dust, pollen, and particles rather than just being a basic filter gives you real peace of mind. The quality feels solid and well made. Installation was super easy, took just a few minutes with no tools needed. For the price this is one of those simple maintenance upgrades that's absolutely worth doing. Your lungs will thank you. Great price and affordable, top choice for replacement in my opinion.

Efficient long lasting. Great Value
Style: CF10735 Classic
These filters (my second one) has lasted me over two years with a little maintenance in between, (removing from time to time to vacuum and shake out the bigger debris.) They do a great job of keeping the cabin air really clean and fresh. 1) Over designed and built (Good thing) installed without effort. 2) Fit and finish is perfect for my 2016 Genesis G80 3) Carbon filter works well but after about six months it no longer absorbs orders, This is excepted especially when I have not swapped it out for over two years. 4) Great value and honestly I should be replacing these cabin filters out ever six months for efficiency and order control. Note: When I decided to replace it the filter held up structurally as the day I installed it. The charcoal beads where all intact as well.

Excellent Factory Replacement and a Simple DIY Upgrade
This EPAuto engine air filter is an outstanding, cost-effective replacement for standard factory filters. The build quality is excellent, featuring a durable rubber gasket that creates a tight, reliable seal within the air box to prevent any unfiltered air from bypassing the element. Installing it is a incredibly straightforward task that takes less than five minutes and requires no tools. It offers the exact same performance as premium drugstore or dealership options at a fraction of the cost. Highly recommended for routine vehicle maintenance. Note: Fits perfectly on my Subaru Legacy 2018!
