Complete upper and partial lower grill block (temp) '09 cobalt

[Burnt]

I used scotts extreme application tape to make a temporary upper block, and some clear packing tape for a partial lower block. The pics are after about a week of driving around in mainly rainy weather....it's held up surprisingly well

I included the edge of the hood as well, to help airflow a little more

it's getting really cold here, so hopefully it will at least help the engine heat up faster

If anyone has any suggestions on how to improve, i'll take em




Also...I was curious about my spoiler.....is it purely cosmetic or does it help aerodynamically?

Its not too pretty, but it'll work.

The rear spoiler is a toss up. Tuft testing is the best way to know for sure.
