2007 Chevy Cobalt

With the stock filter out of the way, we note that the lower airbox shell (which is reused with this GMPP kit) pulls its air from a tube leading down and forward to the area beneath the headlight. There's actually a full separate silencer down there, but getting at it pretty much requires pulling the front bumper cover off, so you'll have to wait to see it until our next issue (when we yank the bumper cover and install a sweet ground effects kit complete with in-fender external DVD screens). Seriously though, we've seen it-and it's a free- flowing, nonrestrictive piece, so there's no sense in getting down there and ripping it out.
