AIR HOG oiled blue Air filter review
I heard about this filter on a 7.3 Facebook site. I had excellent previous experience buying engine specific parts for my diesel powered pick up trucks. I bought the kit and opted for the AIR HOG BLUE, they were out of the blue ‘breathable’ pre filter bags. It showed up a few days later, and is an awesome filter. I easily watched a link they provided showing how to quickly install the filter. I removed my old FORD stock set up, installed the new one in less than 5 minutes. I am super impressed with this filter set up! One thing they don’t even tell you is that with the AIR HOG the ‘end cap’ of the filter that is usually just a big molded piece of rubber, well this one has a reverse conical filter built into it, so it’s really 2 filters in one, absolutely amazing! That kind of took it over the top for me. Now I can actually hear my engine breathe, and I can hear the turbo much better. My truck runs better and I am very happy with this relatively inexpensive purchase that gave such a big improvement. Buy it, instal it, be happy

Great kit
Easy install, went right in on my 2002 7.3 just had to cut the airbag away from the battery bottom. Took about 20-30 mins start to finish. She is breathing nice and easy now!
