Spark Plug Iridium Power - Denso Iridium Power 5344

["Spark Plug - Iridium Power", "Gap .044"]

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 Power spark plugs feature ultra-fine iridium electrodes for improved ignitability, better fuel economy, and enhanced performance. Original equipment on many performance applications, these plugs deliver reliable starting and smooth power delivery.
