We made a bit of trip over to our friends at Extreme Performance out in Goodyear to do a few installs and dyno runs using some of our more popular F150 EcoBoost intakes, one of which was this Airaid cold air intake designed for 3.5L EcoBoost, 3.7L V6, and 5.0L V8 F150s. The intake dropped in easily in about 15 minutes (and we were bad children and didn't follow Airaid's instructions), making this one of the easiest and simple cold air intakes available for the EcoBoost F150.
Airaid actually does provide remarkably good instructions on their website, but their install vehicle is a 5.0L V8. The process is exactly the same and the Coyote-powered F150 uses the exact same air box location, but we figured, why not?
The first step of the process was to disconnect the MAF sensor wiring harness and remove the MAF sensor from the factory housing. Next, pull off the top lid of the factory air box by prying up its metal clips, pull out the stock disposable air filter element and set them both aside.
After disassembling the stock hardware, we transferred the MAF sensor into Airaid's housing. The housing has provisions for both a MAP sensor and MAF sensor, so make sure you reinstall the sensor in the correct slot. While this was going on, we assembled the filter's metal frame using the supplied hardware.
From there, we did a test fit of Airaid's housing onto the stock inlet tubing to find the best angle for the MAF sensor to hook back into the wiring harness. Satisfied, we moved on to the filter assembly.
We set the filter down in the bottom half of the OEM air box assembly and made sure that the filter's neck lined up with Airaid's MAF housing before we dropped in the frame.
With all of fitments looking good, we installed the frame assembly on top of the bottom half of the stock air box, which uses the the factory metal clips and tabs to stay perfectly in place.
Now came the hardest part: the weather stripping. In theory, you're just supposed to pop this on the frame. In practice, trying to make that 90 degree bend in the corner stay put is kind of a pain. Whatever. We soldiered through it, tightened all of our clamps and fittings, and gave everything a good shake or two to make sure it was all actually together.
With the intake installed, we prepared for our truck's dyno runs. Earlier in the day we did a bone stock run with 91 octane fuel and managed to pull a surprising high 357.97 horsepower and 385.45 lb-ft of torque.
In our first comparison dyno run, we paired the Airaid intake with a 91 octane "Race" tune from an Edge CTS tuner and dash monitor to see what would happen. We hit an impressive 371.79 horsepower and 456.8 lb-ft of torque. Not too shabby.
We returned the truck to stock with the Edge CTS and prepared to upload one of SCT Performance's EcoBoost tunes using one of their X-Calibrator 3 handheld tuners. We plugged in the SCT and let it do its thing... which took kind of a long time, around five or six minutes. Despite the delay, the 91 octane performance tune was uploaded successfully and we were ready for our next dyno run.
We want to thank Marty and the guys over at Extreme Performance for making some time for us, not to mention Airaid, Edge, and SCT for letting us throw on their performance gear and do some serious testing and installation work. Thanks again!
