Cold Air Intake Build

[Nathan in MI]

I like it, Justin! One thing that might make it work a bit better is to put some sort of heat shield material on the inside of your box. Being that it's metal, the engine bay heat could heat the whole box up and prevent you from getting as cold air as you could. It may not make much difference, but hey, it can't hurt anything!

I would waste my time and cash doing something else than expirementing with CAI's. The most your gonna get is like 5hp. I'd do something else more benificial to the car.

I picked up the materials cheap at the local hardware store. A big part of it is looks. I don't like seein' that big filter just hangin' there. I like 'em boxed in.

A lot of people would put a lot more effort and money in for 5hp. CAI if done right seem like cheap performance to me. They do change the sound of the engine a bit, making it more aggressive. They also make it easier to get at some things. So as long as you don't waste too much money on your cai, then _I_ think it's a good investment. I can't wait to get around to mine.

I redid the airbox yesterday out of boredom. Still looks like crap to me, but it keeps the engine heat off the filter. I made this box a 1/2" small in most dimensions. Riveted the end on for a cleaner look, too. Little black plug in the top of the box is where I stick the screwdriver through to get to the filter's hose clamp. Also included is a pic of how it would look without a box.

What did you use to attach the pipe to the T.B? If its something made by a compay, what is the part number? I'm sick of my plumbing reducer, its so ugly

I went to O'rielly's Autoparts and found a TB adapter. I believe it is a 3". I had to use the rubber adapter that came with the tube, too, so that the 3" adapter would fit decent on the pipe. Adapter that came with the pipe was only around 2.5" diameter. 3" adapter at the store was about $7.

Hmm, we dont got o'reilys up here. Stupid useless partsource. Guess i'm gonna have to take a trip to the speedshop. Think i'm gonna scrap the ammo box idea and just use the injen tube and make a box for it. Would you mind takin a picture of the box you made for me monterey?

I used a roll of tin flashing from the hardware store. Cut it with an angle grinder. The sheet for the box is ~30" long. The depth of the box is 7.5". The folds are 7". I folded the metal to form the box, then bent a lip on one end. I drilled holes and riveted that lip to the other end of the sheet to make the box. Next, I traced the end of the box on another sheet of tin, measured out about 3/4" from each side, and cut the cover out. Also, I traced the end of the tube in the center of the cover (it was a bitch to cut out). After cutting out the hole for the tube, I put a trim strip on there to prevent scratching of the tube. It also helps to seal it up. I bent the 3/4" flaps on the cover and ensured a snug fit to the box. Drilled it and riveted it on. Drilled a 1/2" hole to gain access to the hose clamp screw, sanded it, and painted it. The box just sets in the car and comes out with the tube. Easy as can be.

I made my box to be able to come out separate from the tube,makes it a little easier when your just wanting to change the air filter,as you don't need to remove the entire CAI. Good Job Though.
