Morning all,
Could somebody tell me what injectors I can upgrade to for 4.6 gems using the existing fuel rail, I know the Ford ones from a mustang fit but I cannot find any concrete part numbers anywhere, so many conflicting comments, u know there's a thread on here but I cannot find it, and please only comments from those who know it works, thank

Anyone...

I don't have concrete part numbers as these are very confusing BUT you need 8 19lb gen2 yellow top injectors. Gen 2 have a metal bottom section and a plastic top section. Simple! These are a perfect fit complete with injector clip grooves. These will power standard and moderate upgrade 4.6.
Marc Adams sells gen 3 that fit(tornado systems)
