1f2e-b4a Injectors
 

Hey guys this is my first post here and I wanted to ask a question/clarify. I searched all over for this injector part number to see if it would work and basically found nothing. I have an 01 with the 4.0L and that’s supposed to have a flow rate of 22.5 at 49 psi stock. Now these injectors I’m looking at are from an 02 mustang with the 3.8L (1f2e-b4a) and these injectors say they have a rate of 23 at 43.5 psi. So when you convert that to 49psi it should be 24.4 right? And if that is correct then would these work on the 01 XJ given the 1.9 difference?

You should be able to run them. If they don't work out for you let me know and I'll get you set up.

Thank you for the reply. I’ll get them in later this week and give an update.

Update: I’ve done some more research and on a couple different websites it lists an interchange part number, and actually one of the interchange part numbers is the ford #19 XF2E-C4B.
also I found a guy with a 2000 TJ running them with no issues.
The only thing I found on this forum about them was someone saying they wouldn’t work because they didn’t have enough flow. (Even tho they already flow more). Of course I’ll update with my experience later this week when I don’t have to work. But these should work perfectly fine and it’s yet another fuel injector that can be added to the list of compatible injectors.

I'm sure he will be happy to hear your results.

I don't have my notes.
What're 1f2e-b4a injectors all about and how do they and Bosch -161 injectors compare to each other ?

Hey bud, looking to see what the outcome of using these injectors was? Did you end up using the1f2e-b4e injectors?
