Installed the new Airaid yesterday. First thing I noticed is it's a lot different working in the engine bay of the truck vs than the Mustang I had! I'm 5' 9" on a good day so a step ladder was a must! LOL

So here's some pics from the install... it was 13 degrees out so only took a few quick snapshots!

Stock intake tube removed... Hey, there's a valve cover under there!




Stock intake vs the new Airaid intake tube:




The Airaid box attached the stock lower half.




Intake tube just sitting in the box. The bolt on the bottom right to attach the tube to the box was a bit inconvenient to put in.




Only thing that was a bit of a hassle was plugging the MAF harness back in.. the MAF harness has a kind of big plastic L that was almost right up against the Airaid box:



Now the wire was not pinched against the box but was a little to close for comfort for me... So I snipped the zip tie that was holding the wires in the plastic L and was able to move the wire down out of the way...



(sorry, no picture of the wires out of the way... 13 degrees and my finger tips were getting numb! LOL)

And then... TA-DA!



Now my impressions and observations...

Installation: Very straight forward. Good instructions. There was one slight mistake. The instruction lists 2 button head bolts to attach the intake tube to the box when in fact the bolts were allen wrench heads. Not a big deal at all... just need to be aware you'll need an allen wrench not a socket wrench. (of course you already need a smaller allen wrench for installing the MAF). Took me about 90 minutes from the time I opened the box to the time closed the hood... that included time to snap pictures and move my step ladder!

Fit and finish: Overall, very nice. Looks great under the hood!

Data: Took it for a 30 mile drive last night. Long term fuel trims looked good. Fuel trims locked in at 0.0% to -1.6%. A lot of the time they were -0.8% with the occasional -2.3%.

Did a few WOT (wide open throttle) runs. The A/F looked good also, with the A/F staying about the same as the stock A/F. Nice thing about the new Fords... they come stock with wideband O2s!

Ok, so it was 13 degrees out so it was kind of hard to tell how much warm/hot air the Airaid will actually pull in. In theory it seals up against the hood... however you can see in the pictures that box has some gaps in it. Now all that being said, the intake air temps (IAT) were reading the same as the ambient (outside) temp... some times it would read 1 degree above ambient temp, however for the most part it was the same. This was while the truck was moving. I haven't done an idling test to see how quick the IATs will climb. But my first impression is the slight gaps in the box really don't let much hot engine bay air in. Will do further tests... especially this summer!

MPG.... ok.. to soon to tell, but my first impression here is my MPG is definitely better. How much, not sure... WILD guess would be 1 to maybe 2 MPG... Doesn't seem a lot but when you drive 30,000 miles a year it adds up!

Overall, very happy with my purchase! Oh, and one last thing, at WOT the truck definitely has more of a GROWL!!! And the engine bay looks sooooo much better!
