Upgraded the air intake to a Safari snorkel. No CAI's on my 4x4!! The mitsu stock intake is pretty waterproof (uses the fender), but I wanted to raise it out of the dust and possible water immersion. Depends on how you use your rig of course, but cold air intakes are very vulnerable to the elements...
I do have a K&N E1012 inside that very waterproof airbox, so I can clean it out regularly...
