Air temperature sensor rubber grommet was missing. Aside from those two issues, it would probably take 15 minutes including removing the old device. The whole block is simply inserted away from the 3 clamps. The instructions say to install the airbox and then the pipe to the filter, but I recommend doing this while the CAI is not in the truck so it's a lot easier. There seems to be a little more power and the exhaust seems a little louder. but i have yet to get a solid idea of mpg, i will update in a few weeks. The sound is not at all like that of a stainless steel air intake like K&N or Injen, it almost sounds like a bad pulley bearing instead of the FOOM FOOM of the stainless steel version, but it's not unpleasant. Except for the missing socket I would give 5 stars. and crankcase ventilation tube.
