Per NGK's description of their collaboration with AMG in designing the engine's plugs:
"NGK’s ILZKAR7A10 iridium spark plug has been chosen for OE fitment to the 365kW, 6.3-litre V8 power unit developed by AMG for use in high-performance derivatives of Mercedes models. In this case, the main requirement was for the slimmest possible spark plug with sufficient performance, in order to leave as much space as possible in the cylinder heads for both valves and coolant passages. To satisfy this need, NGK developed this new plug with a 12mm thread, but a 14mm hexagon and a slimmer ceramic insulator. The length remains 26.5mm."
