HummerGuy -> Home Depot and Pep Boys - Customization heaven (8/11/2006 9:08:23 AM)

In the past I have made custom intake systems for my cars using materials from these wonderful man-stores (as my wife likes to call them). This weekend I'm going to take a stroll there and see if I can find any tubing or air ducts to cheaply eliminate the resonance filter box between the air intake and the throttle body. There has to be something out there. Then I'm going to buy myself some of that engine insulation that is supposed to block heat from being absorbed into whatever you wrap it around, and wrap whatever tubes and ducts I buy in it, also make a custom cover for the airbox that completely surrounds it with the stuff.
If I find an air duct material that is the same diameter as the original, I'm going to cut the hose/air box right after the MAF and connect a straight tube from there into the throttle body.
Last time I did this was on my Isuzu Rodeo. I used thick cardboard and duct tape to create the box, then cut the insulation to match every surface of the cover, in which I used more duct tape to tape the insulation to the box. I used thick wire ties to attach the rest of the pieces to the air intake vents. It may sound a little ghetto, but it looked nice, and believe it or not, it really did make a noticable difference.
When I had my Scion xB, I bought a couple of flexible radiator hoses from Pep Boys and attached them to the Air box intake where the hoses were sucking air from underneath the front bumper, and it kinda worked like Ram Air on the GM cars. I actually ended up doing it for a few other people since they liked it so much.
I'll take pics of my endevours and we'll see if it does one bit of good. I like doing these things and figuring out how to make something better, so it should be interesting. It's cheaper, and probably has the same effect if done properly. Obviously you have to make it as least-restrictive as possible for it to work and make a difference.
Please, if I am a fool for thinking this, let me know, but it has worked on my cars of the past.
