short rams are going to give you good throttle response and are loud. CAI's give you some good HP gains up top. Get a 3" CAI and be done with it. Short rams have a hard time up top. By the way, don't spend a crap load of money on one either. Get a good 3" CAI off of eBay and then buy a K&N filter and you're set. I just bought a 3" off of eBay for 30 bucks and I already have an AEM dryflow filter that I got for 45 at the auto parts store. So that's $75 for a CAI that's just as good as the $200 AEM's, Injen's, ect...
Like Pete said, there have been endless threads/debates on this, and the verdict is: zero difference in max Hp gain with a SRI and a CAI of the same diameter, but the CAI has a little hump in the middle of the curve.
Bam.
Ok, maybe one Hp... the blue is obviously the CAI.
If you live in rain/snow weather, SRI wil be a lot less of a hassle, but if you live in a warm dry climate go with the CAI. Reason bein is that in the winer time you gotta clean your CAI filter constantly, and during rain you MAY have a very slight chance of hydrolocking your car.
