I was one of the R&D vehicles used by AFE to produce their sealed short ram intake. Since they put it on my car I definitely noticed a difference in the response and power. I'm not saying its a huge difference because its just an intake but it is a noticeable one. I love the sound it produces, its more of a "beefy" aggressive type sound and far from "ricey". I've also noticed the 2nd gear lag to be a little less noticeable. They wanted to produce an intake that could be a direct fit without any cutting or permanent modification being done, and one that can produce max power achieved from a short ram intake and it is a job well done. This companies background is awesome and has people that came from the best companies now on their team producing and designing these products.
