Choosing Spark Plugs

Choosing Spark Plugs

It’s important to choose the right spark plug for your engine, especially for consistent, easy starting. We recommend that you change your spark plug every 100 hours or every season, whichever comes first.

Replacing your spark plug:

  • Ensures consistent spark

  • More reliable starting

  • Improves fuel economy
