I don't see why more fuel would need to be added in? Changing the stock air intake tube isn't going to the change the fact that the engine is only going to demand X amount of air.

In my experience with this engine, a MSD TFI Blaster II Coil made no difference over my stock one. But I did use Ford Racing plug wires, just because they are better quality than you get at the parts house. Also ran autolight or motocraft copper core (the cheap ones) in just about every Ford I've owned including my 5.0L. Also ran copper core A/C delcos in my old built up 327 with out any issues or complaints. There definitely wasn't any question in my mind that a platinum plug or a plug with multiple ground electrodes were going to unlock any "hidden" horse power in my N/A engines. Forced induction is where a coil upgrade or special plugs will come into play.
Bigger injectors will only cause problems, the 14lb/s injectors were also used in low performance 5.0Ls Fords, among other engines. The computer is programmed expecting the injectors to flow a certain amount of fuel. BTDT

It really doesn't do too bad for it's displacement. But it is an engine that was no longer used after '92, they are getting old and tired.
