Champion spark plug, Copper Plus. D14

H-D #4, one range colder. M18 X 1.5 thread. 1/2" (12.7mm) short reach. Used with a 24mm spark plug spanner. This D14 (H-D #4) is one range colder (runs at a lower temperature/dissipates heat faster) than the standard D16 (H-D #3) spark plug. This D16 is available as MCS 931600. The cooler running properties make this D14 better suited to high-speed riding, such as extended motorway use. The spark plug has a copper core centre electrode and comes with the patented Ultraseal™ coated shell, to help keep the spark plug free from corrosion for a longer period.
