what fuel injectors work with our cars like mustang or what also what years will fit or are they all the same??

 

many are the same. not all. but ltx, lsx can use bosch or other ford made injectors. check out racetronics website, might be racetronix cant remember but they sell fuel pumps and a ton of injectors. just bought a set of 42# from here myself. they have from stock to 80+#

 

There are a few different choices that will work as replacements.
Are you looking to upgrade?

 

SVO (or FMS), Bosch, Accel and Delphi are all pretty good injectors for our cars.
