Skip the CAI, and get the SVT airbox/snorkel with a drop-in K&N. People seem to consistently report better gains on this setup than any of the available CAI's
What's the difference between the stock zx3 airbox/snorkel and the SVT one? I already have the K&N drop in lifetime filter. If there is a big difference in the way it gets air to the throttle body and it is actually getting colder air then I could get the SVT one and keep my filter to drop in it.
