Air Intake
Hello everyone. I am new to the Ford family. I just bought a 2005 Ford F150, Crew cab, 5.4L engine. I'm wondering what's the best air intake that will give me the most horsepower, torque, and fuel economy

welcome to FTE and the Ford family , I went with the Airaid MIT (modular intake tube ) on my 04 F150 screw with the 5.4 , It replaces the the tube that runs from the airbox to the fender with a different tube but leaves the stock airbox. I also replaced the filter with a K&N replacement filter it seemed to help the truck breathe easier and I did notice a improvement in mpg and power . MPG increase was about .5-1 mpg not a bad deal for about 140 bucks invested

I had problems with the airaid cold air intake, the mit is fine but with small improvements. The cold air intake will give you the power you want but you might want to go with one that attaches into the throttle body better than the airaid so you dont get the check engine light.

Stevo410, Your post got me thinking so I went to the hardware store today and bought a PVC schedule 40 3" elbow and a short piece of PVC 3" pipe. After removing the bellow looking piece at the end of the air tube, the elbow slipped over the tube snugly. I cut the pipe to fit between the elbow and stick into the hole between the left headlight and radiator. A small amount of trimming to the end of the pipe was required to clear the corner of the parking light back. A little black paint and it doesn't look too bad. This along with the K&N seemed to let the lead sled breathe a little easier. I have been keeping track of the milage so I will see if it makes a difference.

The MIT from airaid is not a CAI it is just a replacement air intake tube it still retains the the factory airbox but it reroutes the the opening to behind the headlight . I like it because it looks good and for 92.00 and free shipping I think it works better than anything I could have made myself

Hmm... $92.00 vs $20.00 with a little sweat. I'll take the latter, I don't care what it looks like since no one is going to see it under the hood, I'm only concerned with the end results in power and better MPG's. Besides, $92.00 is a lot of $$ to spend on a bent section of tubing.

The more I looked at the PCV 90, the less I liked it. Went back to the hardware store and looked around a little more. I found a "3 inch qwik-ell", it is shaped just like the pvc 90 but is rubber and comes with the hose clamps. Got it installed this morning and actually looks like it belongs in an engine compartment. I have spent around $20 and have an extra pvc 90 for my next plumbing project.

I agree with transam396 in regard to the factory intake being restrictive. I'm not trying to put down the airaid or any other CAI, I just think these systems are way overpriced. I located a few websites that sell aluminized mandrel bent tube in any dia. needed... for $24.00 shipped. Still alot cheaper than purchasing a CAI system. I think for a total of $35.00 for all necessary parts, I could build one that closely mirrors the airaid system, except I'll attached a flair opening at the inlet to catch as much as possible. I will post results and photos of the project when complete.
