I'm new to the forum and planning to buy the AFE stage 2 CAI at http://4wheelonline.com since the offer is good. I was wondering if anyone here has this kind of cold air intake. How do you like it and how's the sound? I'm not expecting huge improvement but I just want to know if this can boost the horsepower even a little. By the way, I have a 07 4runner 4.7L. Thanks for any help.
