NGK V-Power Spark Plug Box of 4 (BKR5E)

The NGK 7938 is a V-Power spark plug designed to improve ignitability. Its unique v-cut in the center electrode directs the spark to the electrode's edge, promoting a faster spark development. The plug features trivalent metal plating for superior corrosion and anti-seizing resistance, corrugated ribs to prevent flashover, and a pure alumina silicate ceramic insulator for strength and heat transfer.

Constructed with a copper core for heat removal and triple seals to prevent leakage, this spark plug has a 14mm thread diameter, 1.25mm thread pitch, and a gasket seat type. It offers a 19mm (3/4") reach and a 5/8" (16mm) hex size, with a solid terminal type. The center electrode is made of nickel with a V-cut design, while the ground electrode is also nickel with a standard type. This is a resistor spark plug with a gap of .035" (0.9mm).
