NGK IKR7D-4759 Iridium Spark Plug 4759 - One-piece, Precious Metal Type

【NGK IKR7D-4759 Iridium Plug 4759 Integrated Type, Double Precious Metal Type】
■Product Description
High-performance plug that improves both fuel efficiency and acceleration
Iridium IX plugs are high-performance plugs that achieve faster flame propagation compared to standard plugs and feature a thermo edge on the insulator tip to improve resistance to fouling.

Specifications
Iridium IX plugs offer better ignitability than standard plugs, leading to improved fuel efficiency thanks to excellent combustion efficiency!
Outstanding ignitability with a fine center electrode!
NGK Spark Plugs was the first in the world to adopt an iridium alloy!
Iridium IX plugs are high-performance plugs that have faster flame propagation and less energy loss (quenching effect) compared to standard plugs.
Thermo Edge is exclusive to NGK Spark Plugs!
High performance lasts longer because it resists fouling!
The thermo edge, which generates minute discharges, is designed at the tip of the insulator. It burns off carbon deposits on the insulator during prolonged low-speed driving with minute discharges, consistently maintaining the plug's high ignition performance.
The ultra-fine iridium alloy center electrode improves electric field strength, generating a more powerful 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.
