Having a CAI is pretty much the cheapest and easiest way to add more hp to your ride. That being said, We do carry quite a few brands of cold air intake such as K&N, Injen, AEM, APR, Green etc. We tend to mostly sell K&N for the simple fact that they're quality, they work and they won't void the warranty* on most cars.

*verify with your dealer to see if it voids warranty first.
