Relocating the air filter.
Relocating the air filter.
01 SCAB 5.4L, 4x4, Procharged. I don't like the stock position of the air filter with the blower. It's in the engine compartment sucking up all the hot air. I like move down and forward into the wheel well. Has anyone done this with theirs?

I did with my old 97, but I didn't have the procharger, did it with 4" aluminum exhaust tubing and a couple of 90's,clamps and some silicon hose(my preference) opened up the stock opening from the fenderwell and ran a 90 into it and placed the airfilter inside the fender well. Wasn't hard just time consuming.
ONELOWF, it looks your air filter is still in the engine compartment, just like mine. I can see the only direction to go with it is into the fenderwell. I'll need to cut the stock openning larger and place the filter in there. I was thinking of using some flex tubing.

I have read that air temps are +- 50* in the engine cpmpartment as compared to the wheel well depending on ambient air temp. I have also heard that it is not that big a difference, and that a straight run of pipe ahead of the mass air is best for tuning.... that's how I got to design I have.
EDIT: Another easy temp lowering device would be an efan, or fans on your intercooler. I have one 12"er on my 12" x 18" cooler. You could go with two 6"ers easily, and wire them together through a single fan controller.

i would suggest not trying to go through the hole in the fenderwell. it is too cramped in there to support enough air flow for the blower. i had fabbed up a ram air setup at one time using flex hose and cutting open the hole bigger just like you said. i lost power doing this because the air filter just couldnt get enough air to the motor, it was like sucking it in through a straw.
i wish i could remember where the pictures were, but what i would suggest is using some rubber 90's and straight pieces, or 4 inch PVC, and running the filter down behind your air dam/bumper cover, and closing off the area from the motor by using sheetmetal, or i have seen one person use a rubbermaid trash can (yeah seriously and it looked awesome) by cutting it to fit the area.
you might want to cut out the flat metal shelf that the air filter used to sit on (that comes off the fender well) this will open up a lot more area for you to move things around and maneuver tubing.

You can replace your present expansion tank with a tiny Cobra R unit. (cost about $42) This opens up the front and allows you to run a long pipe down the front below the headlight. You would then mount your larger air filter down there.
The trick way to go is with Mike Dunn's (Madenterprise) Procharger intake set-up. It actually gains you a coupla pounds of boost.
I will be contacting him as soon as I have saved up the Benjamins.

Mike's intake is great..here is a pic of the setup I had

I had removed the left headlight and cut the opening larger in the radiator support behind it to let in more air...I never logged air temps before or after to tell if it made it any better but it didnt cost me anything either

Weird,
Just did kinda the same thing to mine just didn't look at the thread first. i have th powerdyne, and I ran the hose down behind the charger to the front of my air dam where i mounted my air filter. i have e fans too so this makes a difference. i have to go tomorrow and get some piping to finish it off. hopefully will get some pics on here soon.

Now we're talking. Thanks raider and desperado, that's what I was originally thinking of doing. I didn't know about the Cobra R unit, I was wondering what to do with the stock expansion tank. The Cobra R makes more sense. One of these days I'll get Mikes intakes, they're a little spendy. Right now I just want to move that air filter because when I'm sitting in traffic in over 100* heat, the truck is sucking alot of hot air and it doesn't want to move very quickly. Thanks for the ideas everyone.

Mike at Madenterprise http://www.madenterprise.com/F150.htm sells them as do Ford dealers from their "Ford Racing" catalog.
