Credit cards aside, both my cars are on storage insurance right now and I don't feel like asking if I'm covered in other cars, though I probably am.

I wouldn't feel comfortable renting someone's car off CL. Yikes.

Anyway. While I try to get someone to jump in and tackle my cowl water leak for a dollar, I'm trying to scheme up a way to get more fresh air into the car.

My truck has a fresh air foot vent that ducts directly from the cowl down around the side and onto my left foot. It's the best thing that carmakers ever abandoned. I want to do something similar, since the Civic HVAC fan sucks, for some reason it never wants to stay on the 100% cool setting, and sometimes a whif of exhaust gets mixed in (more of a nuisance than safety hazard).

I want to make it low drag, so NACA ducts are being heavily considered and high pressure zones targeted. Options:

1. NACA duct from the front of the door, halfway down, with a hole through the door and a vent hole where the speaker used to be. I could make a small interior cover or door to keep cold air out. This is a turbulent, low pressure (?) area, so overall flow volume is a wild card.

2. NACA duct(s) in the center trailing edge of the hood (like a Ferrari F40!). Dryer vent tubing down, through the firewall and into the footwell. High pressure area! But a lot of ducting, possibly leading to pressure losses. Probably hard to plumb. Hard to keep water out.

3. Roof vent. Cheap. Direct. High drag, noisy, doesn't point at feet, possibly high maintenance for a car that sits outside.

Any other ideas? I'd like to put nice, fresh air at my feet with as little drag and fuss as possible.
