Keep ignition strong and the engine running cleanly.
Spark plug inspection and replacement for scheduled maintenance, misfires and hard starting.
Ignition maintenance
Use the right plug and the right replacement interval.
Spark plug design and service life vary by engine. Worn or fouled plugs can contribute to hard starting, misfires and poor performance, but those symptoms can also have other causes.
If a warning light is on or the engine runs roughly, begin with diagnostics rather than assuming plugs alone will solve the problem.
