BMW E80, E82, E9X N54/N55 135I/335I INTERCOOLER

Regular price $659.00 Sale

WPI is proud to carry Ambient Thermal Management's reintroduced stepped core intercooler for 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.


  • 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
