The Cobb FMIC and others all are straight forward installs. The only thing that you have to "cut" is the inner front grill vents and remove the vent motor. If you need to see how it is install, you can go on Youtube. There's a lot of videos on installing the FMIC. I don't like cutting anything on my truck especially the frame but if you are looking to do a lot of steep angle off roading and need that approach angle because you are crawling up a big-ass rock or something then you need to get all that done. Personally if I knew that I am getting into that kind of rock crawling, I'll get a Jeep with a 4" lift!!!
