NGK IFR6J11-7658 Iridium Spark Plug 7658 - One-Piece, Dual Precious Metal Type

【NGK IFR6J11-7658 Iridium Spark Plug 7658 One-piece, Double Precious Metal Type】
■Product Description
High-performance spark plug for improved fuel efficiency and acceleration.
Iridium IX spark plugs offer faster flame propagation compared to standard spark plugs, and feature a thermo-edge at the insulator tip to improve plug fouling resistance, making them high-performance spark plugs.

Specifications
Iridium IX spark plugs offer better ignitability than standard spark plugs, leading to improved fuel efficiency through exceptional combustion efficiency!
Ultra-fine center electrode for outstanding ignitability!
NGK Spark Plugs were the first in the world to adopt iridium alloy!
Compared to standard spark plugs, Iridium IX spark 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!
Sustained high performance due to reduced fouling!
The thermo-edge, where micro-discharges occur, is designed into the insulator tip. This micro-discharge burns off carbon deposited on the insulator during prolonged low-speed driving, constantly maintaining high ignition performance of the spark plug.
The ultra-fine iridium alloy center electrode improves electric field strength, generating a more powerful spark with lower voltage.
The spark is concentrated at the tip of the center electrode, ensuring consistently stable combustion and contributing to improved fuel efficiency.
