NGK CR7EIA-9-91175 Iridium Spark Plug 91175 Screw type One Precious Metal type

【NGK CR7EIA-9-91175 Iridium Spark Plug 91175 Screw Type Single Precious Metal Type】
■Product Description
High-performance spark plug that improves both fuel efficiency and acceleration
Compared to standard spark plugs, Iridium IX plugs offer faster flame propagation and feature a thermo-edge at the insulator tip to improve resistance to fouling, making them high-performance spark plugs.

Specifications
Iridium IX plugs offer better ignitability than standard plugs, leading to excellent fuel efficiency and improved mileage!
Exceptional ignitability with a fine-wire center electrode!
NGK Spark Plugs was the first in the world to adopt iridium alloy!
Compared to standard plugs, Iridium IX plugs offer faster flame propagation and less energy loss (quenching effect), making them high-performance spark plugs.
Thermo-edge is exclusive to NGK spark plugs!
High performance is maintained because it resists fouling!
A thermo-edge, which creates a micro-discharge, is designed at the tip of the insulator. This micro-discharge burns off carbon deposited on the insulator during long periods of low-speed driving, consistently maintaining the plug's high ignition performance.
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.
