how to mod the grill of my 06 Corolla?

Cover it up with some corrugated plastic.

Don't use nails though , they fall out and puncture the over-pressured tires ;)

Coroplast + small holes in the plastic + zip ties= 3% to 5% increase in mpg at highway speeds

What thickness Coroplast should I get?

And where would I find installation instructions for this grill? Even just basic ones...

I just finished my partial grill block on my 06 grand caravan. You can take a look in the Aero Mod section.
