These tips were bought from Dynomite Diesel and used on my truck for about 70k. I replaced them cause I wanted to go back to stock. Truck ran perfect when I took them out, idled smooth and routinely got 18. 5 to 19. 5 meticulously hand-calculated mileage. They will throw some black smoke when you step on it but they're supposed to, they are 90hp. Make me an offer!
