  • Compatible Replacement: These spark plug replacements are designed for MTD 951-10292, 751-10292 and Torch Engine 131-039 models. It is an ignition part designed for small internal combustion engines.
  • Fast response: The spark plug converts the 10,000-20,000V high-voltage current generated by the ignition coil into an electric spark through the gap between the center electrode and the side electrode, instantly igniting the mixture in the engine cylinder. For example, when starting the lawn mower, the spark plug discharge can complete the ignition within 0.001 seconds, ensuring the engine's fast response.

No, car spark plugs are generally not suitable for small engines. Lawn mower plugs have different heat ranges, thread sizes, and electrode designs tailored for the lower RPMs and specific cooling needs of small engines.
