[OKXXFE]

I know this has been discussed and that the best way for me to learn is to just do it, however I do like to listen to others thoughts and experiences prior to diving in.

So, the cage is a 2009 coupe FWD w/5sp. I've done no modifications as yet, but first up will be an upper grill block leaving the lower open ( 'cause I'm in OK and it'll be summer soon).
Since I'm leaving the lower grill open to the radiator, I want to maximize the air flow through it by forming a ram scoop/duct from the front bumper grill to and around the front of the radiator. My thinking is that it should provide MORE than adequate cooling during my commute ( 100mi/day all interstate) and possibly better flow with less turbulence.
While under the car I should also make an engine bay belly pan from the bumper to the cab. This should also function to keep the engine bay warmer and help my WAI without having to duct to the exhaust minifold.

Any thoughts or suggestions are welcome and appreciated!
