Project F-150 Ecoboost – Making Serious Power with Garrett’s Powermax Twin Turbo and Intercooler Upgrade

The Garrett intercooler is raised into place.  Even though it is a lot bigger than the stock unit, with the shutter assembly gone, it goes right into place and fits exactly into the rubber vibration absorbing OEM mounts. Thanks to the great design of the Garrett intercoooler this part of the process is super simple.

The lower core support is bolted into place and the charge pipes are hooked up just like stock.

With the new intercooler in place, it’s time to put the bumper and trim back in place.

The bumper and trim and bolted back in place in reverse order of the disassembly.

The new Garrett intercooler is looking pretty impressive in there!  This is going to make a serious difference in charge air temperature.

We ran the truck with the Garrett intercooler using the same protocol as our original test. We also uploaded the OEM tune and put the license plate back on.  The difference in charge air temps was impressive!  Once the system heat soaked and stabilized our median charge air temps were now 118 degrees, a 57-degree improvement over stock!

The Garrett intercooler upgrade for the Ford EcoBoost F-150 makes a huge difference in air charge temps, is easy to install and fits perfectly. If you have stock turbos with a tune that increases boost the use of an upgraded intercooler is extremely important due to the high charge temperatures that the stock turbos make with higher than stock boost. The Garrett intercooler is a perfect choice.


  1. I’m currently shopping for an Ecoboost F150, the stock intercooler setup just does not makes sense to me. First, with the acres of real estate on the front of an F150, why did they feel the need to put the licence plate right in front of the intercooler opening, covering 80% of it? Second, shutters? really? I mean I understand shutters on a radiator for warm up, but on an intercooler? And I don’t buy the aero benefit… with as much penny pinching as oems do, there’s no way that minuscule aero benefit could justify the price. My money is on the condensation build up Ford suffers with on their turbo cars. But to me thats like using pain killers to deal with a broken bone rather than casting it… I do kinda like the idea of fan on the intercooler tho… prolly helps with low speed high load situations that a truck could see..

      1. With the amazing prevalence of turbochargers on vehicles these days, and every tuning company offering a “stage 1” tune that increases boost pressure and fuel delivery, it makes me wonder how many other platforms fall victim to insane intake temperatures when pushed like this. All of the twin turbo German stuff, the turbo 4pot 2.0 everythings etc.

    1. AJ Hartman built a 3.5EB SN95 with the MT82. I bet it’s a riot!
      I wish the package was a little smaller. It would be a fun swap engine if the bay is wide enough.

      1. And then got boned by dyno procedures… ah, NASA.

        But yeah, again, it seems fun. I wonder if the Link GDI ECU would run one of these well.

  2. Did I miss you testing the new intercooler with the same aftermarket tune you ran on the OE turbo/intercooler setup that increased the temps a bunch? If not, did you and what where the temps?

  3. Jeeezlus, power is waaay too easy these days. 435whp on a Superflow on pump gas through a truck drivetrain wasn’t something you could bolt on without sacrifice (comfort, driveability, etc). Now? No problem, hell, you could even finance the parts! 🙂

    1. True words. The 5.0 V8 trucks have 2650 Eaton bolt on supercharger kits that put out 550-600whp all day. It’s insanity.

  4. Hey Ya’ll, I just installed the same Garrett Intercooler on my 2019 F-150 Limited HO 3,5L Eco Boost, I all ready have a built and tuned motor with stock turbos, So looking forward to cooler side temps !
