NGK ILMAR7A8-91375 Long Iridium Spark Plug 91375 One-Piece, Double Precious Metal Type

【NGK ILMAR7A8-91375 Long Iridium Plug 91375 Integrated Dual Noble Metal Type】
■Product Description
High-performance spark plug that improves fuel efficiency and acceleration
Iridium IX plugs have a faster flame propagation than standard plugs, and also feature a thermo edge at the tip of the insulator, making them high-performance plugs with improved resistance to fouling.

Specifications
Iridium IX plugs offer excellent ignitability and superior fuel efficiency compared to standard plugs, leading to improved fuel economy!
Excellent ignitability with a super fine center electrode!
NGK Spark Plugs was the first in the world to adopt iridium alloy!
Iridium IX plugs are high-performance plugs that offer faster flame propagation and less energy loss (quenching effect) compared to standard plugs.
Thermo edge is exclusive to NGK Spark Plugs!
Maintains high performance because it's less prone to fouling!
The thermo edge, which creates micro-discharges, is designed at the tip of the insulator. This burns off carbon adhering to the insulator during prolonged low-speed driving with micro-discharges, constantly maintaining the plug's high ignition performance.
The ultra-fine iridium alloy center electrode improves electric field strength, generating a stronger spark at lower voltage.
Since the spark concentrates at the tip of the center electrode, stable combustion is always achieved, leading to improved fuel efficiency.
