Like the others said a good tune and a cold air kit will wake the car up for sure but I wouldn't waste the money on the boss intake, i saw zero usable gains with it
No to the CAI....
Both manual and auto 5.0's I have owned picked up with the Boss intake. It is a worthwhile investment if you have the supporting mods. If you aren't willing to spin the motor high and have the supporting mods for it, it will be a hindrance.
