My new custom cold air intake
El cheapo. Cost me just over 30 bucks. I think it turned out nicely.
3" 90 degree PVC elbow
3" 45 degree PVC elbow
3" straight PVC pipe cut to fit
$25 Autozone special open element filter
500 degree heat resistant engine paint, "Ford red"

Lemme know what you think. I know someone will complain about me being ghetto or whatever, but I really like it and I think it turned out nice, esp. for under 40 bucks.

Looks good but it's not really "cold air" till you block off the air cleaner from the engine compartment.

Hehe sorry 84TransAm, I just had to get every possible angle, I know. 
Thanks for the compliments, guys.
John Millican, any suggestions on how to block off the cleaner, and will it really be worth it?

Looks sweet. I decided not to make my one out of PCV piping because that can melt or go bad quickly. I made mine out of exhaust tubing. I noticed a nice improvement out of it. Good job on making your own though.

good excuse to post a pic of mine. Mine was out of mandrel bent 3" exhaust tubing.
yours does look good, and looks great considering its about 1/3 the price it cost to build mine

The PVC is holding up just fine, haven't had any problems. Plus, my stock intake is a thinner, seamingly weaker plastic than the PVC I replaced it with, so...
86FyrBrd, that looks great.
Thanks for the compliments, all.
Hg, It does make a little bit of a sucking noise which is neat, though I can't hear it unless I'm under the hood... but then again I'm practically running open exhaust right now until my Hooker cat-back comes in, so that doesn't help.

I did pretty much the same thing about a month ago. I used PVC also. That is the better choice, the exhaust tubing heats up more. I made one out of exhaust tubing also to try, and the air coming into the engine( I have access to a snap-on scanner) was warmer that w/ the PVC.
good for now
Thats cool you were able to make it. But for the future for you, I like the idea of the exhaust tubing b/c you don't want any chance of any thing melting cracking, but for now you got by cheap.

somwhere I read that PVC lets off toxic fumes when heated up.

Just think, you use it in your house everyday to drain +100* water outta the tub/shower, or especially a dishwasher. It's nice to see some ingenuity still happening in the hot rod world. After all, that's what hot rodding really is.

BTW, if you're concerned about heat, use "B"vent flue pipe for water heaters, furnaces,etc. It's used for running exhaust fumes while touching drywall. I'd say that's pretty good.

Mine has 3" Rubber that goes around the pipe and around the MAF, then used clamps.

Yes, it has never gotten near hot enough in that pipe to melt anything... and I took it out the other night and shot some footage for Motorsport Connection by doing some donuts and such, and it seems to be holding up just fine. My only problem so far is that the underside of the hood barely touches the pipe, so that heat protection junk gets it dirty.
No biggie though.
My original plan (I may still do it if I get bored one day) was to make a kind of dual-intake setup. I bought a "t-pipe" PVC connector and actually have the piping needed to make a dual open element intake. It's probably kinda redundant and unnecessary though, but I do think it would look neat to see that red piping going down into both front wells
. Plus I don't think I've ever seen a dual open element intake on a Firebird. I'd have to relocate the battery to the trunk or something though, which is what's holding me back for now. One day when I have nothing to do (and my trunk is actually together.
). I kinda like that idea anyway because it will make it extremely easy for me to wire my amp and such, if I were to put it in that side locking compartment or something, since there are little vent holes in it if I'm not mistaken. That and, relocating weight to the rear is a good thing, no?
