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.

Denso Iridium TT (Twin-Tip) spark plugs feature iridium center electrodes and platinum ground electrodes for maximum longevity and consistent performance. Engineered to OE specifications with service intervals up to 100,000 miles.
