I am wondering if I have a set of 03-04 injectors and change the nozzles to 04.5-07 nozzles will they work in the 04.5-07 trucks? Or are there differences other than just the nozzles, anyone know for sure? Thanks

 

there are minor differences/improvements done to newer bodies, but functionaly, yes you can run 04.5- tips on any year bodies.

match the tips to the year of the truck and your ok

 

same bodies, different nozzles.

 

03/04 have 8 holes and a wider spray angle, vs 5 holes for the 04.5+ injector tips.
