I removed the factory ram air plug in front of the factory air box area. Unfortunately it mounts from the front(behind grill & headlight bucket). My thoughts are screw a like sized bolt(instead of screw)from the front without the plastic plug. Now screw a washer & bolt on from air box side creating a stud. Now I can mount or remove the plug when & if I want quickly & easily. Ill throw some pics up later tonight of the factory hole. I'm gonna open the hole up even more & make my own plug & even a little shroud behind the grill. But the factory plug & hole will work also if you don't wanna make it bigger. The factory hole is 3.5"x4". It can be opened to 4"x7" with minimal work. Also before shoving the bolts through to make studs you could add some screen to the mix.
