Which Injector for stock 1988 5.0 -- Motorcraft or Bosch?

Searched the forum archives....lots of chatter over the years for upgrading injectors for performance but little discussion on stock applications.  I have a 1988 Cougar XR7 and want to replace ALL of my 14lb/hr injectors with new, not refurb.  Bosch and Motorcraft (4-hole) appear to be the most common and close in price. I prefer to stick with OEM but does anybody have any experience or rumors for the Bosch?

Bosch made the OEM injectors for Ford.  Pretty sure they still do.....

I wouldn't bother replacing stock injectors. Do an engine cylinder balance test. If it passes twice in a row it meets or exceeds factory spec and fuel injectors will gain you nothing.

You can also have your fuel injectors rebuilt, they basically just clean and flow test them. Really isn't much to go wrong inside one.

I honestly dont think you could exceed the cost of a new car buy installing new *stock* parts everywhere in your coug our tbird. Its just plain impossible. You could revamp the entire drivetrain/engine/suspenstion and still come out ahead.

If the injectors are working correctly you'll gain nothing by replacing them with new ones.
