Brandon hooked me up with the Steeda intake for my car and I got around to installing it last week. I'm really happy with it and the sound is amazing, I love the growl it makes around 2,500rpm all the way up to 7,000. I can't wait to get an exhaust on and see how the car sounds then. It really does have a nice boxer engine sound and isn't overbearing at all. Cruising down the freeway you can't even tell it's there, same goes for easy acceleration.
As far as power goes, it feels like the pick up is slightly better with the car, but it's really hard to tell. I have notice an improvement in fuel economy though by about 2.3mpg on average under similar conditions.
I am really glad I went with Steeda over other brands. It looks great in the engine bay and everything fit perfectly. It took maybe 25 minutes to install and everything fit tight and spot on. All I had to do was trim the the rubber that sealed the box to the top of the hood.
