The plugs combine a projected, iridium-tipped center electrode with a single taper-cut nickel ground electrode and a factory-set 0.044\" (1.1mm) gap. Designed to fit applications requiring a 14mm thread diameter, 1.25mm pitch and a 5\/8\" (16mm) hex, these are intended as direct-replacement components meeting the listed mechanical specifications.\u003c\/p\u003e\n\n\u003ch3\u003eWhat are the exact dimensions and mechanical specs of this NGK plug?\u003c\/h3\u003e\n\u003cp\u003eThe BKR6EIX-11 uses a 14mm thread diameter with a 1.25mm pitch and 19mm (3\/4\") reach.
