I just put one on and it made a big difference. I got it at Fasthemis.com for $230. I think it was the last one they had but they were expecting more this week. It was an easy install with easy to understand directions. The picture posted doesn't have it tipped down into the space as much as mine. There is some adjustment but not a lot. It just rests on the heat shield opening. Overall I am very happy with it.
