Talk to me about them. Worth it? Any performance, sound, and/or mpg improvement? What about water issues (exposed filter and puddles bad for engines, do you have to buy a cover for them?)
I went with the AFE because it's open and was getting the RK Sport functional hood, however these gains were with the factory hood...... More noticeable power gains with RK Sport hood. Will check MPG this weekend.
I went with the KN&N (Auto Anything had it on sale). Easy install with heat shield. Great sound improvement (without being obnoxious). A bit of performance improvement (as seen by the butt-dyno). Haven't noticed any MPG increase, but I spend a lot of time in Tampa traffic, don't think anything could improve MPG's in that kind of driving... :P

Based on the limited research I've done, your account is pretty much on par with others. Better sound, some increased performance (acceleration mostly), but not a noticeable increase in mpgs with the K&N.
The Volants on the other hand have reviewers that say they do notice an MPG increase.
