I'm going to look into making my own intake setup, go
here this actually inspired me to try and make my own intake setup, just be creative look around parts stores and find what you can. Me I'm going to use those silicone/rubber type couplers and 2.5-3 inch exhaust tubing from autozone to do mine, and get a cone filter, and make a heat sheild for it, also be sure to try and get the filter as far from the engine you can, so it don't suck in heat. Good luck.
Also I forgot to mention, they have high temp paint to use on the exhaust piping too, its like 4.99 a can at autozone.
