This is a great filter. Good idea to run the prefilter with this one. Also found get a paper one to have on the side. real dusty times the paper one you can blow out. the oil ones if too clogged the intake will crush the filter. I Keep 2 oil filters per truck that way you aren't waiting for the filter to dry all day while your truck sits idle

Great people easy and very helpful. You guys are great thank you

Great quality filter. With a new clean filter in the air intake box, the truck runs great and EGTs are low.
