Which Injector for stock 1988 5.0 -- Motorcraft or Bosch? February 25, 2016, 07:37:04 PM 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? Quote Selected

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. Quote Selected
