PROFILE

An ARM FMIC upgrade is one of the best modifications for your 335i because not only does it yield an average of 25whp and 27wtq but it does so consistently. "How?" you may ask. When you increase power with a tune  for example, you are increasing boost pressure and ultimately heat in the engine. When the ECU (DME) detects too much heat, it will actually reduce timing and limit the amount of power the engine can produce in order to avoid damage. What an ARM intercooler upgrade does for your 335i is keep the intake air temperature in the ECU's "safe zone", allowing it to maximize all the modifications you have on your car. 

 

DYNO PROVEN

We tested our N54-powered 135i with the following performance upgrades: 

-ARM 3" Catless Downpipes
-ARM N54 Charge Pipe w/TiAL bov
-ARM N54 Dual Cone Intake
-And of course the ARM 5" Stepped FMIC. 

In addition, we were using the infamous Burger Motorsports JB4 to turn up the boost and manage the tuning on our beloved N54. The results were impressive: a massive 408.8whp and 480.4wtq!

LOWER IAT's

How is that extra power made? The temperature of the charged air going into the engine, or IAT (Intake Air Temperature), is a key metric. This factor is essential because the cooler the temperature of the charged air, the more dense it becomes, and the increased density equals more power with the proper tuning. The higher the IAT is, the less power the car will make.

In an independent test, the OEM intercooler reached a very high, power-robbing temperature of 151 degrees Fahrenheit. The same car equipped with the ARM 5" Stepped intercooler was able to keep its power up with a very cool 106 degrees Fahrenheit. That's an impressive 45 degrees cooler than the OEM intercooler!

47% BIGGER THAN OEM

The ARM Motorsports 335i FMIC increases cooling efficiency and power on your N54 or N55 equipped 335i by using a 5" stepped core which maximizes intercooler size to almost 47% BIGGER than OEM.  This is achieved without the need for irreversible cutting or trimming to your bumper. It retains all the OEM crash bars and bumper pads as well.

The ARM 5" intercooler is constructed of a bar and plate design and will allow for consistent performance. It reduces heat-soak and minimizes the chance of your engine reducing boost and timing due to high IAT's. 
 

FIRST OF ITS KIND

The ARM 5” FMIC is the first ever intercooler upgrade for the E90 335i engineered with CAD-designed CNC aluminum connectors for you to utilize either the OEM intercooler hoses or the  ARM FMIC Hose Upgrade. Opting to utilize the OEM connectors will make for a faster installation. While upgrading your 335i to the massive ARM 3" intercooler hoses, you will be giving your 335i maximum airflow by removing any restriction the OEM connections may have on the charged air.

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.
