About DENSO® Spark Plugs
DENSO® is a global leader in spark plug technology, offering advanced solutions designed to deliver long service life, high performance, and reduced maintenance requirements for gas engine applications. With strong OEM expertise and continuous innovation, DENSO remains at the forefront of spark plug development for demanding operating conditions.
The latest DENSO DOUBLE IRIDIUM (DDI) spark plug technology significantly extends spark plug lifespan while reducing maintenance needs compared to conventional and competing spark plugs. DDI spark plugs are particularly effective in biogas engine applications, where harsh combustion conditions demand superior durability and ignition stability.
In addition, the Iridium Saver and Iridium Saver Performer spark plug ranges are engineered for high-compression lean-burn engines. These spark plugs maximize engine performance, enhance durability, and increase service intervals—making them an ideal choice for operators seeking reliability and long-term cost efficiency.
