Just a heads up... Banks tends to build more and spend alot more time and money on R&D for Duramax engines. Doesn't surprise me that they fall short on anything but Duramax.I've got the airaids on 2 of my 6.7 rams and I'm very pleased with them. They are built really well, and the filters have a 6" inlet and have a very nice venturi built on it. Banks is junk IMO I had a set up on my 06 5.9 and it was junk the scoop is a crock just stuffs the air box full of chit. S/B are ok but I don't like the fact that you have to pull the covers off to clean the filter.
