I made this today from a strong, flexible, semi transparent plastic. I got it from work (free). My car suffers from a very long warm up time in the winter. I'm hoping blocking the main source of air will improve warm up.

Was this a better choice than blocking the space between the bumper and hood? I could easily do that as well.

My only other mods are 52 psi in the tires, mudflaps and antenna removed.

Feel free to pick apart my cavaliers aerodynamics, I read the drag coefficient is .36 which amazes me it's so much worse than my cobras .32 (in avatar).

Thanks,
Michael
