Iridium IX Spark Plug | Gap 0.044in
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.
NGK Iridium IX spark plugs feature ultra-fine 0.6mm iridium electrodes for improved ignitability and extended service life up to 100,000 miles. As original equipment on many vehicles, these plugs deliver superior performance and reliability.
