no, I bet 10 bucks you will have no gains.
If you are trying to make better airflow a flat sheet is not the way to do it. At least put some dimples is the sheet metal (like a golf ball). But seriously, don't waste your time, Hyundai would have done it for you if it was worth it.

You'd get better aerodynamic gains by doing the following.
#1 Lowering the car
#2. Installing a lower air dam to prevent air from going under the car
#3. Installing lower side skirts to prevent air from going under the car from the sides
#4. Install a rear defuser to ease the wake created by the car/help join under car air with over car air which reduces turbulence, decreases drag and decreases rear lift.
Once you've done those 4 things....
Installing undercar venturi's leading to the rear defuser will help create downforce at speed and also clean up under car airflow/turbulence.
I can reccomend several good aerodynamics books if you are really interested.

There was a product made for gen2 vws years ago that used an inverted wing shape engine undertray coupled with a specially designed front airdam. It was good for pulling air through the radiator and created enough of a vacuum to actually pull brake dust IN through the rims instead of expelling it (kept the rims cleaner)
From what I remember of it, the airdam was stock sized in the middle, but it had lower corners. The inverted wing shape bolted to the middle of the airdam between the lower corners of the dam. They allowed air under the car beneath the engine, but kept it under control at the sides and where it flowed beneath the engine.

If you want to improve ur areodynamics all you have to do is use DUCT TAP!! yep thats right duct tape.....just tape off any gaps on ur front end such as, where the hood meets the fenders, bumber meets the fender, around the headlights....that should be sufficient enough, BUT if u want more...tape over the entire front bumper laugh.gif .yep thats all lol.gif
