NGK ILZFR6C-K-6645 Iridium Spark Plug 6645 One-piece Double Precious Metal Type

【NGK ILZFR6C-K-6645 Iridium Spark Plug 6645, One-Piece, Double Precious Metal Type】
■Product Description
High-performance spark plug that improves fuel efficiency and acceleration.
Iridium IX spark plugs ignite combustion faster than conventional spark plugs and feature a thermo edge at the tip of the insulator, improving resistance to plug fouling.

Specifications
Iridium IX spark plugs ignite better than conventional spark plugs, leading to superior fuel efficiency!
Ultra-fine center electrode for excellent ignitability!
NGK Spark Plugs was the first in the world to adopt iridium alloy!
Compared to conventional spark plugs, Iridium IX spark plugs have faster flame propagation and less energy loss (quenching effect), making them high-performance spark plugs.
Thermo edge is exclusive to NGK Spark Plugs!
Keeps high performance for a long time because it's resistant to fouling!
The thermo edge, which creates micro-discharges, is designed at the tip of the insulator. Carbon deposits on the insulator from prolonged low-speed driving are burned off by micro-discharges, maintaining the plug's ignition performance at a high level.
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, consistently stable combustion is achieved, leading to improved fuel efficiency.
