It does help the air flow a little better under the rear of the car, but it's not going to really be noticed at all. Just gets rid of the "flat" wall causing turbulence as the air flow exits under the car.

Here is a real diffuser.

I know what a real diffuser is, dude. I was simply stating it is a small improvement over not having it.

I meant to put a exclamation point.

If it extended back to maybe the rear axle a bit more the benefits would be better. A few vents above the winglets to let trapped air escape. 7-10 degree rake eems to work best.
