intake is intake. you wont get much differences between cai and sri. since you have automatic. go with sri. most of people likes thier sri, specially k&n sri. just search around. theres plenty threads about sri vs cai.

I love my AEM SRI, I can tell a little difference (very little) with power and a lot of difference in engine sound. I also love the sound when I shut off the engine. I would give two thumbs up on the AEM SRI

Seriously S2000, we have a ULEV engine (a tiny 1.7L one at that). 90% of your gains with an intake of either kind will be sound only. There are a lot of theories and numbers getting thrown around, but when it comes down to it, you will BARELY feel any increase with an SRI, and I can bet you won't feel much more with a CAI. That said, CAI is nice for the pose factor, and if you want your intake extending down that low, I vote for Injen, because 1) they actually make a model for your tranny and 2) the filter sits behind the bumper, offering you just a TINY bit more protection from the elements than the AEM, which sits below the battery tray somewhat.
