Spark plugs ignite the compressed air/fuel mixture in each cylinder, and their condition directly affects combustion efficiency, fuel economy, and emissions. Signs of worn plugs include: difficulty starting, a rough idle, a hesitation or misfire under acceleration, reduced fuel economy, or a check engine light with misfire codes. Replace spark plugs on schedule - new plugs restore clean ignition performance and can noticeably improve fuel economy.

Champion has been manufacturing spark plugs since 1907, offering reliable ignition products for a wide range of applications. While not a premium performance brand, Champion plugs deliver dependable starting and smooth operation at a good value.
