Anyone have pics of a "homebrew" cold air intake? Not the ram air one. I want to make one, and need help. Thanks.

I'm almost ready to do my intake and get rid of the factory tube that can't handle the boost ..fans finally came in damn 3 months ...
I was wondering would there be any disadvantages to using 4" exaust tubing instead of black PVC sewer pipe think I'll have problems with heat soak ?
the 4"inch pipe will be super smooth inside the only thing that worries me is heat soak i dunno if it's going to be any worse than plastic pipe?
anybody ever done it ? <img border="0" alt="[cheers]" title="" src="graemlins/gr_cheers.gif" />

I don't know dude. I think PVC pipe would soak less heat, but what about where you connect the pieces together, it might blow apart with boost, and metal pipe wouldn't. <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" /> And oxidizr thanks in advance for the pics. No hurry though, dude.

If your gonna use metal tubing get it Jet-Hot coated. If you've ever touched a set of Jet-Hot coated headers a little bit after the car was turned off you know that stuff dissapates heat quickly. <img border="0" title="" alt="[Eek!]" src="gr_eek2.gif" />

I think you can even get it done in black. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

Either that or wrap it in that reflective heat shield stuff. On my old 355 S10 the cat was right below the pass. side floorboard. It actually started burning the paint on the inside when I fired the truck up the first time. <img border="0" title="" alt="[Eek!]" src="gr_eek2.gif" /> I put some of that reflective stuff above the cat and you couldn't even feel the heat on the inside anymore. That would keep alot fo heat outta the pipe also.

How much does the Jet hot cost might be Xpensive to do all the tubing ? something to consider though thanks for the idea

I used standard 4" PVC. Long turn elbow to straight 4" tube, then directly fit to MAF and have a K&N mounted to close it up. It is painted a nice gloss black - looks pretty, but I was afraid it would soak heat, so I have it wrapped in some 1/4" reflective insulation. Created the cold air box similar to a K&N, but added the reflective insulation to it to cut down radiant heat soaking. It is a work in progress.

Thanks Bigtex that is just what I was looking for. I got the 4 inch elbow and a stick of 4 inch pipe today. I was wondering what you used to connect the pipe to the MAF sensor? Also I was going to try to use my DJ Motorsports air shield, but I will probably need to make a new one. What kind of material would you recommend for that? Man this pipe is huge, I bet it out flows all the other pre made pipes out there. Thanks dude.

You will need electric fans for this to fit.

On the elbow to the TB, I used the rubber gasket and clamp off of the stock intake tube. I had to heat the rim of the elbows w/ a torch just a little and squeeze it in to make a tight fit. To the MAF, I was able to do the exact same thing- stock rubber gasket and heat the tube some. To shrink the tube - I made some small cuts about 1/2" into the PVC, then heated lightly w/ a torch. Be careful, too much direct heat will make it catch fire or blacken. Once hot, I was able to bend it inward with my hands. After it cools, use a file and sandpaper to clean up the PVC. This area will be covered by the gasket anyway.

One other thing- I bought some 4" ID stuff from Home Depot. It was pretty thick. It didn't fit properly. I then found some 4" OD tube that was much thinner. It works great.
