Flashpaq/Exhaust/CAI?

[Dr. Evil]

New member here. 2010 JK 6 speed manual with 3.21 gears. It is strictly a local daily driver. 1.5" RK springs (about 2.5" lift) with 33x12.50 Duratrac's, as well as some other suspension pieces. I just received a Superchips Flashpaq and aFe exhaust http://www.4wd.com/Jeep-Engine-Perfo...pn=AFE49-46208. I am just looking to get a bit better throttle response and maybe some hp and mpg increase. Currently getting in the mid 16's local and 17+ on the small amount of highway driving I do. I understand not to expect miracles. For my usage, didn't want to spend $1500 - $2000 (parts+install) on gears. I was thinking about this CAI http://www.4wd.com/Jeep-Engine-Perfo...pn=AFE51-76203. On the forums I am on, most basically HATE CAI's on the JK. Since I don't off road, I am not concerned about water, dust, etc. The general consensus is that they are a waste of money, can damage the engine over time and one should remain stock when it comes to the air box. Most vendors as well as aFe think otherwise but I hope it is not just because they stand to profit off of them. Finally, if this gets installed, is there any benefit to this throttle body spacer http://www.4wd.com/Jeep-Engine-Perfo...pn=AFE46-35002? Can you folks please give me your perspective on the CAI and spacer? Thanks ahead of time.
