I installed this over the weekend. Dropped my egts a bit and does help some with the low end smoke. I also have the crazy Carl's ram tunnel so I had to do some small modifications to get this intake horn on and bolted correctly. The stud you get in the kit needs to be cut down some to work and I had to drill and tap the ram tunnel to get the other 3 stock intake horn bolts to seat all the way. With crazy Carl's ram tunnel it moves the intake horn forward some so you really have the get the straight piece of piping as far in as possible on the 45 degree elbow to clear the horn . I had to use some spray to get the boots on but it wasnt too big of a deal. Overall it was a pretty easy install if ya got some decent tools and spray.
