I did the "mini mouth" mod too. Except I just took the one body rivet off the inner portion and rolled it back and rested it against the back side of the grille.

The butt-o-meter didn't notice a difference, but I do know the ram air effect is real and does boost HP.

$170. for a .25 cent piece of plastic seems a little ridiculous to me.
One of these days I'll pull the fascia and design something out of sheet metal or something.

I'd recommend putting it at a 45* angle to funnel it towards the opening.
Think of taking a hose and squirting it at a plate. The water will bounce everywhere.

Since air behaves like a fluid, that is what is happening right now as you drive down the road.
