NGK ILTR5A-13G-3811 Iridium Spark Plug 3811 Solid Type Double-Precious Metal

【NGK ILTR5A-13G-3811 Iridium Plug 3811 One-piece, Double Noble Metal Type】
■Product Description
High-performance plug that improves both fuel economy and acceleration.
Iridium IX plugs offer faster flame propagation compared to standard plugs, and feature a thermo-edge on the insulator tip to improve resistance to plug fouling, making them high-performance plugs.

Specifications
Iridium IX plugs offer excellent ignitability compared to standard plugs, leading to improved fuel economy due to outstanding combustion efficiency!
Super fine center electrode for excellent ignitability!
NGK Spark Plugs was the first in the world to adopt iridium alloy!
Iridium IX plugs are high-performance plugs with 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 micro-discharges, is designed into the insulator tip. Carbon deposited on the insulator during prolonged low-speed driving is burned off by micro-discharges, maintaining the plug's ignition performance at a consistently high level.
The ultra-fine iridium alloy center electrode improves electric field strength, generating a stronger spark at a lower voltage.
The spark concentrates at the tip of the center electrode, ensuring stable combustion and leading to improved fuel economy.
