im lookin into a CAI and have looked at numerous threads but there seems to be very little input on the nismo CAI....any would be aprriciated, also ur opinions on others, thanx

 

I'm running the Nismo CAI...it works, was easy to install, and has a clean, unpretensious look. I always try to buy Nissan/Nismo parts, as long as they fit the sedan. Just be aware that to truly make any CAI system work properly, you've got to hack out (part of) the black foam bumper filler in the lower left front.
