Can you use them???

[2007 5.9]

I am wondering if one could use 03/04 injector tips on a 04.5+ truck??

I understand that the early CR injectors have a narrower spray angle to spray into the re-entrant style bowl, but could that tight spray also work in a non-re entrant style piston???

I get why they wont work the other way around, but in theory would it work???

did it by accident, so did skynyrd.....he ran them for some time. i noticed much more engine noise, and compared to my buddies truck with 120's (mine ended up being early style 120's) i chugged black smoke...


i pulled them after 3 days, i would like to hear some of the experts chime in!

You're backwards, 03-04 is wider because it is re-entrant style 04.5-07 is not thus sprays at center of bowl and is much tighter pattern.

Whoops!!!

Looks like I got them mixed up...:nail:

Thanks for clearing that up!!!

555 motor injectors (143*) will spray outside a 610 motor's piston bowls with fuel timing increases, and the flatter spray angle won't match well with the 140* dome shape... engine will certainly run, but expect to have knocking, power & longevity issues.

Gives the fuel an identity complex - can't decide which direction to swirl... "am I an entrant or non re-entrant molecule?" :hehe:
