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

You're getting a box of four NGK V-Power spark plugs, part number 7938. These are designed as a direct replacement for many vehicles and off-road applications, offering reliable performance and better ignitability compared to standard nickel plugs. The unique V-cut in the center electrode helps direct the spark to the edge, promoting a faster, more complete burn for quicker engine starts and a smoother idle.

NGK builds these plugs with a high-grade alumina silicate ceramic insulator, which provides excellent strength and helps with heat transfer away from the plug. The center electrode features a special V-cut design, and the ground electrode is concave, both working together to improve ignitability. For easier installation and to prevent corrosion or seizing, the trivalent metal plating on the exterior ensures the plug comes out as easily as it went in. The copper core also aids in heat removal, and triple seals are used to prevent any combustion leaks.
