New to Ford ownweship..dumb question?

[Alienxtx]

I just bought a 2011 Expo with the 5.4, I've noticed that it (like my 2010 F150 work truck) has a crappy intake set-up. By this I mean all the little air boxes coming off of the intake tube. I take it that this is suppose to reduce the Noise coming from the intake?

I was wondering if anyone on here has cut those boxes off and then went back with fiberglass etc to fill in the holes?

I figure that this can do nothing but help the air flow getting the the engine.
I was thinking of maybe doing this to mine this weekend and if it works then I will do it to my work truck too.

Thought?

Thoughts are its a ford take it back and get your money back

Sounds like a lot of effort. I know what you mean about the boxes/baffles, I didn't like it either. Ripped it off, threw it away and put a full K&N CAI on. But by all means, if you want to mess with the plastic and fiberglass, go for it, sounds like an interesting project. I took the easy way out and let the engineers at K&N build mine.

Dib is right, just ditch the stock system for a CAI.

By the way, it's not just Ford that has that kind of stuff. The EPA regs force the manufacturers to do that.

lol Well I am a Toyota fan (help run a toyota only off-road forum) but they dont make anything (with good fuel milage) that fit my family/towing needs. Plus I have over 70k on my work truck (ford) and have had zero problems with it.

I already have the K&N drop in, but dont wanna spend the extra cash for the CAI. I have all the stuf I need fiberglass wise to do it, was just wondering if anyone else had bothred. My 2010 Tacoma I traded in didnt have all that crap on it, but I got a free Volant ram air kit for it, and ended up just putting it on.

You could always just build your own tube to the airbox. You can all the aluminum piping and couplers you need here from 1-4in. http://www.siliconeintakes.com/

Might just do that, I'm going to go ahead and mod the factory one this weekend since I already have the stuff on hand anyway.

Show us pics of the final product.

 

[Alienxtx]

Well do.

Ok I did end up modding the factory tube but it was such a PITA that I went ahead and just ordred some tube and connectors and built my own and put the one I moded on my work truck.

Have you seen any gains in acceleration or power with this setup?

Could you post a picture of the modded factory intake? Just curious to see what it looks like.

I just put it together this morning and have not had a chance to drive it yet. I'll reset the comp this evening before I head home, and let you know.

not my best work, but I was pissed and it started raining on me while I was working on it. And since I decided it wasnt going to end up on my expo I didnt bother smoothing the outside of it very well, just shot some rattle can on it and tossed it on my work truck. With the holes left behind being so close together on the filter side of the tube, it made it very hard to lay out the fiberglass and make it smooth. The inside turned out fine, so air flow is much better, I have noticed a little better throttle response out of the truck now, but have not made a unloaded highway trip yet to see if I picked up any MPG. I would suggest just picking up some tubing and going that route, modding the factory just isnt worth the time/effort IMO. I think Im into the tubing and fitting for $75.

Where did all of the extra stuff on the intake lead to? I have never looked that closely to it to find out.

 

[Alienxtx]

nowhere, it just hangs off of it. I believe its suppose to cut down on noise etc? The one box that comes off of the driverside of the throttle body I just removed and made a cap to cover the hose coming out, all the rest I cut off with a saw then used a drimmel to smooth it out. When I installed it on my work truck I just left the box off of the throttle body for now and put the cap I made on my Expo. I will end up making one for the truck too.

Ok, I just made a unloaded 100 mile trip in my work truck with the modded intake. I'm averaging 20 mpg were before I was only getting 15-16 on this same trip. This was all freeway with the cruise set to 75. Not to shabby imo.

I still have not really got a chance to test the Expo out yet since I rarely drive it. I did order some wrap to go on the aluminum tubing in installed, it really soaks up heat like a sponge and that is not good on performance. Once I wrap it the intake temp will drip and I should really notice I jump in everything.
