I need some help finding the retail part # for the injectors in my motor which came as part of the Roush kit for my 06 GT.On the injectors themselves is # 25386328 and 1307c.In my online searching, its possible Roush lists them as 91546 c01 25386328.These injectors are Delphi units. I called Napa, a couple other parts houses and Dealerships and they said these numbers are not in their system nor do they cross over.Seems strange since they are Delphi brand injectors.Can anyone supply me the retail part # or correct crossover #?Thank you
