Personally I would go with the comptech icebox. It costs about as much as any other brand of CAI but it has a couple great features that make it better in my opinion. First, since the filter is located further town the intake track and the intake is partially covered by the fender it is almost impossible to hydrolock the engine with this intake. Also, the filter location is a lot easier to take out for cleaning.
If you can get on here to type this, you can figure out how to install an intake. Its really easy and it will come with directions. Check out
