NGK Standard Spark Plug (CMR6A)

NGK Standard spark plugs are a well-known choice for reliable performance, often found as original equipment on many engines. This particular plug, the CMR6A, comes in a convenient box of 10, making it a solid option for applications that use multiple spark plugs or for keeping spares on hand. They are built with a pure alumina silicate ceramic insulator, which offers good strength and helps with heat transfer, keeping the plug operating at its best.

What really makes these plugs stand out for ease of use and longevity is the trivalent metal plating. This treatment gives them superior resistance to corrosion and seizing, so when it's time for your next tune-up, they'll come out much easier. Inside, a 98% pure copper core helps dissipate heat effectively and improves conductivity, contributing to consistent performance across a wide range of operating temperatures. The triple gasket sealing is also a key feature, preventing any combustion gases from leaking out.
