CAI or Short ram intakes

i just got my 2003 zx3 last month and sometime in July im going to replace the intake. ive heard pros and cons for CAIs and Short ram intakes. what do you guys think is better to get? taking into consideration: price, gain, maintenance, etc....

Thanks.

Cold air is always better in the long run

i also heard that the CAI would have a better chance of letting water / dirt in because of where its placed. is this true for the focus installation location?

yes
