RE: 99 a4 1.8t air intake...
bleh, make your owwnnnnn.. took me an hour tops.
list of materials:
cone filter
high-heat spray paint 1200 degrees
sheet metal
zipties
Basically what i did, took off stock airbox, took of the MAF, blah blah blah, all that good stuff. Had just the hose sitting there. I put the maf back on, put the filter on the end. Put my heatshield in, drilled 2 SMALL holes in the heatshield, ziptied it to the black bar thats there from the stock box, and its tight as hell, and i sprayed it of course before I put it in, but that high heatshield stuff is AMAZING. I can actually put my hand down by the air filter, and feel the air soooo much cooler. You dont need a high grade steel or metal or anything, just something enough to block heat. The sound when you get on it, is amazing. Gas wise, doubt it. It doesnt provide much performance nor does it help gas milage, because when you first hear that "voooooooop-psssccchh" you immediately wanna do it more and more. but good luck, if you need help, i can help ya.
