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 Laser Iridium spark plugs represent the pinnacle of NGK technology, featuring ultra-fine iridium center electrodes and platinum ground electrodes. Engineered for maximum performance and service life up to 120,000 miles.
