Ok, I posted my first cowl intake in another thread. I used dryer venting and it was ugly as sin, and not very servicable, as removing it would crush the vent. The original below.
I really like the cowl intake, so I went to the junkyard and found this.
That's the intake hose from a mid 80s chevy pickup. I got it for free since the junkyard rarely sells them. More often, they get thrown away. Nobody wants the things around here. Makes for good cheap parts.
I had already drilled this lovely 4 inch hole in the firewall using a holesaw and a burly drill.
Where I had a ridiculous piece of 4" aluminum, which I ripped out.
After trimming the elbowed end at an angle, and slightly shorter to clear the MC reservoir, I was here.
Well, just punch a hole in the bottom of one of the pleats, and cut it there with some tin snips, and shove the thing through the hole.
And just for good measure, I ran a self tapping screw through the tube just to make sure it was secure.
And there you have it. Another angle.
This project cost me $1.48 vs. the 8$ spent on the dryer vent setup. I only had to pay the $1.48 because I needed the one hose clamp, and that was left over from the dryer vent setup.
Edited to add. If you don't have an auto (rubber band lol) then you would cut an oval into the firewall above the brake booster instead of a circle next to the booster like I did. My suggestion would be to take two hole saws of a smaller diameter, probably two inch or so, and cut your two holes, then use a dremel with a cut off wheel and cut it straight between them. This plastic will deform readily, and likely seal better that way than my setup.
Here's a picture of the unused round end positioned where you would need to do it with a manual. It will readily deform to an oval. Just smash it, mark the width of the smashed tube, and use the marks as the outside edge for your hole saw holes. Then trim off the elbow section instead of the other end like I did. You will have a more gradual bend than mine. Put the holes as close to the brake booster as possible, so you clear the hood. Otherwise you may somewhat crush your intake. Though it isn't a problem really, I would avoid it.
