NGK Standard Spark Plug Box of 10 (CMR7A)

NGK is well-known for making reliable ignition components that many manufacturers trust as original equipment. This box of 10 NGK Standard Spark Plugs, part number 7543, uses proven technology that customers have relied on for years.

These plugs feature a pure 98% copper core that helps dissipate heat effectively, keeping the plug at optimal operating temperatures. The insulator is made from high-grade alumina silicate ceramic, which provides strong dielectric performance and better heat transfer. For easier installation and removal, NGK applies a trivalent metal plating to the exterior, giving it superior resistance to corrosion and seizing. The triple gasket sealing is also a notable feature, designed to prevent any combustion gas from leaking out.

NGK Standard spark plugs are constructed for a long service life and consistent performance. This box contains 10 plugs, making it convenient for applications that require multiple spark plugs.
