There are a few intake options out there, but spend the money on the NeedsWings Intake. By far the best bang for the buck mod you can do. It woke my car up more than the upgraded pulley, and the sound alone is worth the cost. NeedsWings is a tuning company that has been around and they know their stuff...

The general recipe for a fast fire is the NeedsWings Intake, NeedsWings Intake Manifolds, ASP 178 or Code 3 Pulley, InMotion Custom Tune, Johnson Intercooler pump. Properly tuned and setup, this will get you in the low 12's
