UPGRADE YOUR 135i/335i FMIC

Ambient Thermal Management is proud to reintroduce the stepped core intercooler back to the E80/E90 BMW market!

SIZE- We've measured the available area in front of the bumper in both depth and height and custom designed an intercooler that makes the most of this space - the result is an intercooler with 56% more frontal area and 56% more core volume than stock.

CORE- ATM is the only FMIC manufacturer producing a stepped core as one single assembly. Our core is custom made to our specifications, including the ambient and charge row height and internal and external fin count. And of course, at the heart of every ATM intercooler core is our unique rounded header bars which act as a velocity stack for the charge rows, increasing the flow efficiency from 80% to 98%.

PLUMBING-ATM opted not to utilize the factory plumbing. The reasoning is simple: the E80/90 series cars utilize restrictive charge pipes that shrink down to less than 2" ID. Our intercooler kit uses 2.5" ID silicone charge pipes and a 2.5" OD aluminum J-Tube (2009+ vehicles).

ENDTANK DESIGN- All endtanks are not created equal. Air likes to flow in a smooth, curved radius just like you see on the rounded cast endtanks of the ATM FMIC. 

The end result is the ATM FMIC's ability to remove more temperature, meet the targeted air flow, and minimize pressure drop in your BMW.

HIGHLIGHTS

  • More core volume than stock? - Yes, 56%
  • More ambient face than stock? - Yes, 56%
  • More charge rows than stock?  - Yes, 13
  • Bar and Plate construction? - Yes, with innovative rounded header bars
  • We also designed the intercooler to sit against the factory heat exchangers, so the radiator fan could still draw ambient air through the core when the vehicle is in low speed situations

    There are a number of independently-tested logs across the web showing the high efficiency of the ATM core. Here are a few:

    WOT from 2nd through 4th:

    2nd comparison WOT 2nd through 4th

    4th gear WOT:

    And another independently tested log:

    ATM started at 87F or 7 degrees over ambient. The pulls both started within 50 RPM over each other as noted by throttle position/RPM. The end of the pull was 113F for a 26F increase.

    Fits the N54 135i/335i from 2007-2011+ and the N55 135i/335i from 2011-2013

    (J-pipe needed for 2009+ models)

    • Utilizes factory mounting points- Yes
    • Requires removal of one time use clamps

    • NO cutting or trimming on most 335i models. 

    • SLIGHT trimming is necessary on the 135i near the Ambient Air Sensor.
