NGK DILKAR7B8-92217 Iridium Spark Plug 92217 One-piece Precious Metal Type

【NGK DILKAR7B8-92217 Iridium Plug 92217 Integrated, Double Precious Metal Type】
■Product Description
High-performance plug that improves both fuel efficiency and acceleration.
Iridium IX plugs have a faster flame propagation than standard plugs, and feature a thermo edge at the tip of the insulator to improve plug fouling, making them high-performance plugs.

Specifications
Iridium IX plugs offer improved ignitability compared to standard plugs, leading to outstanding fuel efficiency!
Exceptional ignitability with a fine center electrode!
NGK Spark Plugs was the first in the world to adopt iridium alloy!
Iridium IX plugs are high-performance plugs with faster flame propagation and less energy loss (flame quenching) compared to standard plugs.
Thermo edge is exclusive to NGK Spark Plugs!
High performance lasts longer because it's resistant to 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, constantly maintaining high plug ignitability.
The fine-diameter iridium alloy center electrode improves electric field strength, generating a more powerful spark at a lower voltage.
The spark concentrates at the tip of the center electrode, always providing stable combustion and contributing to improved fuel efficiency.
