I was looking for a good CAI, but was tired of just seeing the TRD intakes. I came across this intake while searching. I know Injen makes a great kit, so I was sold. It was around $350, which isn't bad. It was pretty quick to install, and even uses a scoop that actually routed cold air from the upper grill area. Not sure about power increases, but throttle response is definitely a little sharper (probably a few hp gained). Talk about a sweet growl though, all the way through the low to mid RPM ranges. Plus, this thing looks great under the hood. Overall, awesome investment.
