Afe stage 2 with prograud 7 filter, yes you do oil it. It fits my 07 5.9 and comes with everything, filter cold air box and torque tube. very little bit has been cut on the bottom of the cold air box cause it was rubbin the intercooler pipe. also there was a rubber strip around the cold air box to seal it to the hood but it only lasted a week before it started falling off so its not there, i ran it this way dont think it makes a difference. I would like to get 250.00 for it and it would be shipping from las vegas, nv. I ran it for 1.5 year only, 20,000 miles. thanks dave
