I searched and was surprised to find very little in the way of CAI info for the 2004-2008 F150. What is the consensus here on CAI's? Worth it? is there really a HP gain, MPG gain? What are some of the trusted models i should look at. I have a 2007 stock F150 SCREW with the 5.4L. Looking at a CAI, Gryphon tuner and exhaust. It's my DD as well as my tow rig for my Wake Surf boat.

I have Been looking at the Roush, Air Raid, K&N. Have any of these actually been dyno tested to prove their HP and MPG gains? Oiled Filter or Dry?

I have one. Zero gains. A little more top end noise. Expensive ornament

Pretty much what SCORGE said. Get custom tunes from MPT or 5 Star, WAY better than canned tunes on any programmer, and not much more expensive. Trust me. I ran the canned tunes until my custom ones came in from MPT, HUGE difference.

This is what Air raid shows for a dyno test.

And you trust advertising claims?

Gotts mod, tuner, and call it a day.

I don't know about horse power, MPG gains or tunes - but for $15 bucks, I got my IAT to run within 0 - 1 degree of ambient temperature.


I pulled the air intake snout out of the fender, bent it 90º forward behind headlight and wire-tied it to trans cooler lines into radiator. Then wrapped 15 dollars of R13 Air-Conditioning duct insulation over the whole dam thing including the Air Box, and taped it up with aluminum ducting tape.


Torque Pro gauges monitoring IAT (and a bunch of other temperatures) reveals it is very effective (as far as ingesting the coldest air possible) Although it looks sorta red-neckish. It used to run 10-20 degrees above ambient, even cruising. In the summer here in South Texas that becomes a problem. If ONLY because the EVAP monitors will not run if IAT is > 100º.

R13 A/C duct insulation does the trick


Filter is still accessible.

Everything temperature
