K&N shipped immediately. The filter was correct for our 500hp cummings in our motorhome. Just now landed on our first outing with the filter installed. Made hill climbing easier and I don't know yet, but based on my experience so far, I may be getting slightly better mileage. Too early to tell. Our coach is an 08 so no DEF. After market exhaust. Standard filter was about $100 per year, or more frequent if driving in dusty situations. This one is pricey, but worth it. Dusty situation, just rinse it.
