I have a 2007 R/T with R&T so I have the Daytona intake. I don't really think I need an aftermarket CAI, and I don't want anymore engine noise (I prefer noise from the back of the car). Does a new K&N filter flow better than a new paper filter? I just want maximum efficiency, and elimination of bottlenecks. I have Blastin' Bobs resonator eliminators on the way. I will also have a Predator tuner soon enough.
