So, in addition to graduating to coil-overs from spacers, I want to also install a cat-back and maybe a CAI. I also noticed that there is a MASS AIR SENSOR from JET available as well as a throttle body spacer. Not that I would actually invest money in these items, but give me the straight scoop on these two items: Do they make any "real-world" difference in HP or fuel economy?
