NGK DILZKAR7C11S-90137 Iridium Spark Plug 90137 One-Piece Twin-Tip Precious Metal Type

[NGK DILZKAR7C11S-90137 Iridium Plug 90137 Integrated, Dual Precious Metal Type]
■Product Description
High-performance plugs that improve both fuel efficiency and acceleration.
Iridium IX plugs offer faster flame propagation compared to standard plugs, and feature a thermo edge at the insulator tip to improve plug fouling, making them high-performance plugs.

Specifications
Iridium IX plugs offer superior ignitability compared to standard plugs, leading to improved fuel efficiency thanks to excellent combustion efficiency!
Exceptional ignitability with a fine-tipped center electrode!
NGK Spark Plugs was the first in the world to adopt iridium alloy!
Compared to standard plugs, Iridium IX plugs are high-performance plugs with faster flame propagation and less energy loss (quenching effect).
Thermo edge is exclusive to NGK Spark Plugs!
Maintains high performance because it resists fouling!
The thermo edge, which generates minute discharges, is designed at the tip of the insulator. It burns off carbon adhering to the insulator during long periods of low-speed driving with minute discharges, consistently maintaining high ignition performance of the plug.
The ultra-fine iridium alloy center electrode improves electric field strength, generating a stronger spark at a lower voltage.
Since the spark is concentrated at the tip of the center electrode, stable combustion is always achieved, leading to improved fuel efficiency.
