I realized there was this DIY forum, so I guess I'll throw this up here in addition to where I had it in Non-Tech.
On Sunday I got bored so I thought about what I could do to my car for little to no money, that would result in some kind of performance gain...Cold Air Intake!!!
My short-ram is actually the old one from my d16 that I cut to fit when I got my b16. I think it might be a little longer then the "real" short-ram for b16s, but you can just use a little more straight PVC to extend the length to where mine is. I mean, the short ram intake I had almost reached to where a CAI would go to behind the bumper so figured why not add a few inches of piping and feed my engine some chilly air.
I used all 3" PVC pipe from Home Depot. There are two 45 degree angles and a 90 degree corner. I know bends cause turbulence but for less than $20 (Canadian) I know I wasn't gonna get AEM quality
Here are pics:
I've heard that with some CAIs you need to remove the bumper to install them, but I was able to just remove a single screw attaching the shroud to the front bumper and I could pull it back enough to get the filter in and reach inside. Having another person would've helped a little bit to hold the filter from the bottom while I attached up top.
One 45 degree bend worked well to position the 90 degree bend exactly over the hole I cut with tin snips. Careful with the cut metal tho, I've got plenty of little cuts on my hands now . I couldn't mount the filter directly to the 90 bend through the hole because the filter was bumping into the wheel shroud underneath. What you can't see is another 45 bend underneath that angles the filter toward the front of the car and away from the wheel. I don't think much water can get past the shroud unless I totally submerge my bumper in a huge puddle. I'll have try to stay away from Florida for a while
The result:
I can definitely feel a little more power in vtec range. It has a much deeper tone now, especially when the vtec kicks in. Is it pretty? Not really, but it was cheap and a good way to spend a couple hours.
It's not a bad little project, and like I said I'm pretty happy with the result. My piping used to get really hot, but now after hard drive it's cool to the touch. I was out for the last hour driving around and holy shit I SWEAR this intake mod has improved my performance. I'm VERY VERY happy with this inexpensive mod, and my throttle response seems the same as before!
