UPGRADE YOUR 135i/335i FMIC
Ambient Thermal Management is proud to reintroduce the stepped core intercooler back to the F20/30 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 67% more frontal area and 59% 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 94%.
PLUMBING- ATM opted to utilize the factory plumbing on this application. The reasoning is simple; Unlike the previous generation E90 series' restrictive charge pipes, the new F30 series charge pipes are more than adequate and provide no restriction to flow.
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.
- More core volume than stock? - Yes, 59%
- More ambient face than stock? - Yes, 67%
- More charge rows than stock? - Yes, 15
- Bar and Plate construction? - Yes, with innovative rounded header bars
Utilizes factory push-lock connections - Yes
- 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

Test 1 - The data log below is a comparison between the stock F30 328 intercooler vs. the ATM intercooler. The scenario was set to log charge air temperatures and pressure before and after the intercoolers for three back to back third gear pulls. Ambient temperatures were 55°F during the stock intercooler test and 53°F during the ATM intercooler test.
The red line indicates the charge temperature before the intercooler.
The blue line indicates the charge temperature after the intercooler.
The black line is charge pressure before the intercooler.
The green line is charge pressure after the intercooler.
Results: Pressure (Delta P) pre vs. post intercooler are near identical between the two intercoolers, ranging between .05-.15 psi.
Temperature (Delta T) pre vs. post intercooler are very different.
The pre-intercooler temperature was 224°F for both intercoolers. The peak post stock intercooler temperature was 48.7°F above the 55°F ambient temperature @ 103.7°F resulting in 71% efficient.
The peak post ATM intercooler temperature was 15.3°F over the 53°F ambient @ 68.3°F resulting in a 91% efficiency!
Test 2-The next data log below is a comparison between the F30 328 stock intercooler vs. the ATM intercooler. In this scenario we tested the intercoolers in a standing start to top of 4th gear pull.
Results: Again the Pressure (Delta P) pre vs. post intercooler are near identical between the two intercoolers.
Again Temperature (Delta T) pre vs. post intercooler are very different.
The pre-intercooler temperature was 223.8°F for the stock intercooler. The peak post stock intercooler temperature was 45.2°F above the 55°F ambient temperature @ 100.2°F resulting in 72% efficient.
The pre intercooler temperature was 222.3°F for the ATM intercooler. The peak post ATM intercooler temperature was 8.9°F over the 53°F ambient @ 61.9°F resulting in a 94% efficiency!
Fits the N55 BMW 335i and 135i from 2012+
- Utilizes factory mounting points- Yes
Requires NO cutting, removal and/or permanent modification
