RAM air intake. By WMS

First off Ram air is a myth for the velocity our cars move.
Also ram air does not mean coming through hood openings.
Ram air is air being pushed/ ramed in through any means possible like a scoop under the chin, hood scoops, Shaker, a tube behind the grill etc...
But there are 2 spots in the shroud where the "Ram Air" comes in fed from the original cold air spot not the original intake tube.
These performed on the 4.6 very well. It's all on the site.

The main idea is bringing in cold air and keeping engine heat away along with the shortest & straightest possible air flow to the intake. Which this does.

No big deal if you don't think it works or believe it's a waste. They are dyno proven to work. It's just different from the others.
I saw this on a 2010 at a car show and the guy loved it and said it dynod 12 hp over stock before he tuned. Then tuned and pulled and got 23hp. It's no better than the others but no worse. I like the clean look and seeing as there is a stang on every corner it's nice to have something different.
