I installed one this year, works pretty good. Not 100% effective, but still a big-time improvement for the stock shield, especially at hwy speeds.
I'm still monkeying with the final position, hence all the Duralast dots. The higher the better for me, I think I can squeeze another 1/2" out of it.
It's not a $360 Aeroflow, but for $95 shipped I give it a thumbs up.
