I bought a set of those and they are Ford Branded and made by Bosch

I have not attempted the install yet
One thing to note that if the originals are slotted at the top for the bracket theses are not and will need to cut a slot to hold them into fuel rail

Also the set I got was not exactly as pictured..

They have the same max flow as the original injectors so I dont really see the point. Maybe mid range or part throttle improves due to the fine spray but would it be noticeable?

The point is to use less fuel for the same output . The 4 hole puts out a finer "mist" . Less unburnt .

I put them in mine, but has been awhile and did not notice much change, but also have not kept a record of gas mileage either. Could have been an improvement there.

Ducks..I assume that slotting to fit the fuel rail is not necessary

No slotting necessary, they were direct fit.

I will try to start measuring mpg. My odometer went out soon after the install and have not checked yet. The car does run very smooth, but not sure if I can say the injectors helped with this. Sorry I cannot lend more feedback on them.
