Colder spark plugs pull heat out of the combustion chamber faster than the stock plugs do. That extra heat margin helps prevent pre-ignition (engine knock) once you start adding boost or a tune that raises cylinder pressure.
why this one — This is Ford's own factory-engineered plug for the Gen 4 VDE 5.0L, so it's a safe, warranty-friendly swap if you're planning to add a tune or supercharger down the road - no guesswork on heat range like you'd get picking a random aftermarket plug.
