DENSO PREMIUM CLASS IRIDIUM LONG LIFE SPARK PLUG
Denso Premium Class Iridium Long Life Spark Plug is fast becoming the standard for today's high-tech engines. Employing a revolutionary 360 degrees laser welding process, Denso has created a spark plug unlike anything on the market today. This particular spark plug is designed for durability under the most extreme conditions, thanks to a patented Iridium alloy that is 6 times harder and 8 times stronger than conventional platinum and can handle temperatures in excess of 4,000 degrees Fahrenheit.
- Features fine-wire iridium center electrode for maximum firing performance and minimum voltage requirements
- Platinum ground electrode resists gas and electrical erosion and corrosion extending service intervals to 100,000 miles
- Tapered cut improves firing performance by reducing quenching
- Withstands higher pressures and temperatures
