4.7 injector upgrades?

I just found out about the I6 guys running 4 hole injectors from crown vics?

My question is do they fit our 4.7 or anything out there for us?

I currently run motocraft injectors off the 99 mustang cobra. They are a 4hole injector and about 3# heavier flow rate over the stock 2 hole 21# injector. Yes they are on my 3.7 but it's the same fuel system as the 4.7 minus two injectors, cylinders....blah blah blah lol

We're they a simple plug and play.
Or do they need engine aftermarket part support to work properly

Haven seen real power gains due to the fact it's running the factory injector calibration. BUT. I would say it does seem to run better and it makes power further into the rpm band (higher up) then stock where power falls off after 5200. As is now, all mods included, mine don't fall off till 6100
