if you plan on making it a cold air intake you'd better put a heat shield between the filter and the engine. the exhaust manifold is on that side and it throws off alot of heat. check out the cheap mods thread in the fab section somebody there has a nice cold air homebrew setup.
Check out my album. I have a home made CAI. I used 3'' pipe from Murrys, one end is expanded to 3 1/16 0r 1/8 fits perfict into stock flex tube. I picked up a filter from www.frozenboost.com.

If you want to get the most out of your CAI, you need to isolate the filter from hot air coming from the engine. So, you need to fab a shield between the motor & your filter. The goal is to totally isolate the filter so that it only receives "outside" air. Simply hangin a cone filter on the end of tube has mistakenly become known as a CAI but really isn't.
You can use the parts you found at the bone yard.. just make sure you do some fab work to isolate that filter.

the way that filter element looks scares the heck out me. i'd wash it and check for damages, because you may need to buy a new filter for it. the intake pipe itself seems pretty solid. and like others have said, isolating the filter from the exhaust radiant heat is key. you could always modify the stock air box and have the filter and intake pipe go into that, or do like what SWCcustom did and make your own heat shield. if you know of anybody with a washing machine or something sitting out on the curb for trash pick-up, you cut a side off and use it to bend and shape into a functioning heat shield.

not a big problem unless you plan on driving through a river. were the filter is located, not much comes into that section of the engine from regular road splash. you're pretty well protected unless you decide to cut a big hole in the wheel well since the filter sits right above that.
