NGK IZFR6K13-6774 Iridium Spark Plug 6774 Integrated, Bi-Noble Metal Type

【NGK IZFR6K13-6774 Iridium Spark Plug 6774 One-Piece Double Precious Metal Type】
■Product Description
High-performance spark plug that improves both fuel economy and acceleration.
Iridium IX spark plugs are high-performance spark plugs that offer faster flame propagation compared to conventional spark plugs, and feature a thermo-edge at the tip of the insulator to improve resistance to fouling.

Specifications
Iridium IX spark plugs offer better ignitability and significantly improved fuel efficiency compared to conventional spark plugs, thanks to their excellent combustion efficiency!
Excellent ignitability with a very fine center electrode!
NGK spark plugs were the first in the world to adopt an iridium alloy!
Iridium IX spark plugs are high-performance spark plugs with faster flame propagation and less energy loss (quenching effect) compared to conventional spark plugs.
Thermo-edge is exclusive to NGK spark plugs!
Resists fouling, maintaining high performance!
The thermo-edge, which generates micro-discharges, is designed into the tip of the insulator. It burns off carbon deposits on the insulator during prolonged low-speed driving using micro-discharges, constantly maintaining high spark plug ignition performance.
The ultra-fine diameter iridium alloy center electrode improves electric field strength, generating a more powerful spark at lower voltages.
Since the spark is concentrated at the tip of the center electrode, stable combustion is consistently achieved, leading to improved fuel economy.
