I say free because I built this with stuff I already had in my basement. What you are looking at is the bottom portion of the air filter box sitting upside down on the kitchen table before installation. The 2 and 1/4 inch hose is off a shop vac and at the end acting as a scoop is a portion of a quart plastic oil container. After drilling a 2 inch hole in the bottom of the air filter box I attached the hose using some brackets that came from an old Erector set.

I took it for a test drive but it's hard to tell if there is any extra noise but I haven't had it on the freeway yet. I've also got the K&N air filter so it wasn't totally free. That cost me 37 bucks. This is quite similar to the Mountune CAI but cost about $263 less to make.

I was going to drill holes into the air deflector and mount the scoop to the back of the deflector but chickened out and the scoop hangs just below the deflector in the path of cold air.

What do you guys think? Mountune claims theirs picks up 21% more air and this should do about the same.

Oh and by the way that is not a real shotgun. It's an air soft gun I use on the squirrels raiding the bird feeder out back. :)

I like it! I might end up doing the same and get the short shift kit, both for the price of one :-D

I took it for a spin on the freeway yesterday and I honestly can't say I hear any difference or feel any difference. More cold air should be available but I'm wondering if it's really needed? After all the stock air box is fed cold air through the front scoop and maybe that provides plenty?

Just wondering, did you notice any difference before with just the K&N filter?

No, not really. Although I only drove it for a day or two before modding the air box. The car is still pretty quiet although you do get some intake noise at full throttle which I would attribute to the sound symposer. The Injen CAI I had on my Fiesta SE made a much greater difference in sound than here with just the K&N and the second cold air hose.

What are you going to secure it to? It seems like there isnt anything down there that wouldn't let it hang lower than the front bumper. The stock airbox is only 6" above the bottom of the engine bay. I am considering just using a dremel and cutting the bottom of the airbox out. I live in AZ so no risk of getting water in there but a little worried about dust.
