People around here are whole heartedly against it but have you considered the WeaponR SW?
I'll say that the stupid thing whistles like mad on my car (and I was recently told by WeaponR that "it just does that" and they "can't figure it out") but I don't know if that's a universal experience and they claim gains beyond that of your average SRI.
Also, Thai.95LCoupe apparently has 1 CAI left (though, you'd have to buy the filter) - I've had my eye on it but my cash flow is shot so someone should pick it up!

Personally, I woudln't spend the $$ on the injen SRI (though, I'd consider the old CAI if I could find one) - at least WeaponR claims to have done some research and you can see it (there's clearly a velocity stack inside the pipe - whether or not it makes a difference is open to discussion).
