sheesh, 03- 04 8 hole injector nozzles, 04.5-07 5 hole nozzles. they also have different spray angles to direct the fuel into the piston bowls that are also different on the trucks. you should not put the wrong ones in either way. The bodies are the same, however newer bodies are out that address some issues........... be sure of your truck, its parts, and their uses. easiest way to check for 5 hole vs 8 hole is not by simply looking, but by spraying wd40 through the nozzle with the needle removed with the red straw over a piece of paper to see the spray patern/ count the holes. Needlesare supposed to stay with nozzles, as in they become matched.

Not true. Neither will will last long with dirty fuel. Both will last and work well with extra filtration. There is NO difference in the bodies or tips other than number of holes and spray angle.
