I sold the truck in the fall of 20, but I had 24K miles on the the injectors. They did have just a bit of hazing once up to temp.
Haven't talked to the guy that bought it, so it must still be running good.
Who's using them? Any dislikes? What do you do with your truck?
I'm trying to decide if it's worth it for me. I have a 19 3500 about 75% of the miles are towing my 14K lb. 5th wheel.
