Comparison - Injen Short Ram PLUS Extension

I am having a hard time trying to decide which intake is best for my 96 Civic. I live in Canada and we got some bad winters so I'm looking at the Injen IS Short Ram and getting the CAI extension for it which I can use during the summer and take off in the winter. I'm not planning to go racing (yet), I just want to have better acceleration and power in the low to mid-range area. How does would this setup (the short ram with the CAI extension on) compare to the AEM CAI or the Injen RD CAI in terms of power. Would it be better if I just get the AEM CAI with the bypass? I heard that Injen is better than AEM in terms of power but is that the Injen RD and not the IS?
Thanks a lot!

i dont know much about those products but you really wont be able tell much of a anythink. (that goes for any intake)
either way they are just a pipe you bolt on. shouldnt take more that 20 min.

in most cases, CAI or RAM air on a stock engine drops power on lower end. Read this post..

I say leave your stock airbox alone if you car is mostly stock.

Oh well, too late I already took advantage of a good deal on an SRI. My car is still stock now but it won't be for long. I've been on an crazy spending spree (for a student anyway). Thanks for your reply though, at least now I know.
