A bigger gap means a bigger spark. If the system can produce sufficient voltage to jumb that gap without misfire, you get lower emissions, better economy and more power. As a side note, multi-ground-electrode plugs dont give more sparks, just theoretically last longer.

that is way to much gap for a stock ignition. .44 is the correct gap for your plugs. only if you were running an msd coil and or 6Abox would you gap your plugs that much.

Plug gap should be listed on the Emission diagram sticker under the hood. Usually on the radiator support. Should have engine size listed and type of emissions installed at the fatory.

I also have a 1996 5.0, the following refers
Chilton's Manual (Manual #26664) Page 1-30 says plug gap 0.044
Haynes Manual (Manual #36058) Page 1-3 says plug gap 0.044
Both manuals have a note that says to refer to the Emission Control Label in the engine compartment, and to use the values on the label if different from the manual.
Emission Control Label in engine compartment says spark plug gap is .052-.056
Are we all thoroughly confused now?
