I heard that the correct part number for the ford motorsport 30lb injectors was F1SE-E5A and 0280150945. Now when I asked the person selling these what the numbers said on the sides of the injectors he said they were F1SE-E9A and 280150945. I think he meant to put down 0280150945, but the other one should be F1SE-E5A and not E9A, right? Does the 5 look like a 9 somehow? Or is this a completely different injector? Thanks for any help.

 

0 280 150 945 appears to be the bosch part # just from doing a quick search so I wouldn't worry about that. As far as the other letter/numbersequence I'm not sure but they could be 30 #ers, maybe a difference batch or series?
