It really depends on what you want m8.
You will always wonder what your car will be like with a CAI,won't you.
So go and try my car first to see what you think then make you own mind up.
With a CAI you get its own advantage like more induction noise(which i love) and it's own psttt noise.
So just come and look for me and try it for yourself
As for power wise they are probably the same till you get on the open road
