I have a Steeda short ram. I noticed a better response in acceleration but nothing worth writing home about. Focal is right about the build quality though it is top notch. Plus you gotta love that sound that you get witha short ram!!
If you are going to get a short ram like the Steeda you may as well spend less money and get the MAC intake. Mostly on the Steeda you are just paying for that sticker they put on there. Not much difference in the build quality from the Steeda to the MAC.
The Volant is definitely the most popular intake and I've never heard anyone say a bad thing about it. Seems to give the most consistent gains as well. It's what I'm getting once I have the money to start working on my car again.
i was promised mine by today but no show. do a search under steeda or garyk to see why i am ditching aem. the intakes have been done for a while. i have been told since before xmas that they needed filters. as of mon i was promised it would ship this week.
