Well, I wanted to build my own custom Cold Air Box for quite a while and finally I did it. Let me know what do you think:

Looks good, I never thought of making it that way. Please tell what you used for around the edges especially around the intake hole. Thanks

smth_hckr - It is relatively easy to take off. It is not fixed with any screws but just fitted well. However, since the filter intake tube is fitted through it, to remove it you'd need to slip off the intake pipe. I'd say it takes 30 seconds. I don't know if the improvement will be very noticeble especially since it is cold out.

smartjay28 - All there is is a piece of sheet metal that I cut using the shape i created with cardboard + rubber edges. I cut the metal using metal cutters and I cut a hole for the intake tube using dremel tool. Price was $10 for sheet metal + $5 for the rubber tubing. Tool price - $12 for the metal cutters (i wanted them anyway) and I used James92LS' (Thanks for your help James!) dremel tool to cut the hole.

stalker - thanks for the idea for the box. I combined what I learned from you with some knowledge from the internet to build this. For both edges and intake hole I used a rubber tube (this particular one was 6 feet of Windshield Washer Vacuum Tubing that I got from local Schucks for around $5) that I cut open on one side. I don't know if this small design would work in your case because your intake is shorter. I used this design because mine extends all the way to the end of the engine compartment because of the TCS.
Also, even though I like how your CAB is black, I'm thinking I'll leave mine shiny to reflect the heat more.

That black paint is 1000 degree heat resistant paint. Leaving it shiny will not make any difference in temp. If the sun were a factor then it would be a diff story. Darker colors absorb more heat.

you should try getting the boxes ceramic coated or powder coated. that would work much better than a high temp paint. all that means is the paint wont liquify until that temp, it doesnt block nearly any sort of temperature. the metal does a much better job at that.

if you want to really make that worthwhile, get it powder coated or ceramic coated. it would be reasonably inexpensive for something small like that.

Thanks Doc, I used it because it's fast drying and doesn' t look glossy not so much for the temperature. ;) IMO It's realy not worth the trouble of getting the box ceramic coated for such minimal gains.

Ah, I see what you mean. Well you could probably get that powder coated for $15, and it would be a much stronger coating than the spray paint is, so you would not have to worry about it getting all scratched up..but thats just what I would do.

Looks very good, fits in place wonderfully (both of you)
