Description

The NGK 3365 CMR6H Nickel Spark Plug is a compact, high-performance plug designed for small engine and handheld power equipment applications. Built for durability and consistent ignition, this plug features a copper core for efficient heat dissipation and a standard nickel electrode for dependable performance.

The pure alumina silicate ceramic insulator ensures superior strength and heat transfer, supporting reliable operation in demanding environments. Triple seals help prevent leakage and maintain consistent combustion.

With its compact 10mm thread design and bantam size, the CMR6H is ideal for modern lightweight equipment where space is limited.
