NGK ILKAR7B11-4912 Long Iridium Spark Plug 4912 One-Piece Double Precious Metal Type

【NGK ILKAR7B11-4912 Long Iridium Spark Plug 4912 One-Piece Double Precious Metal Type】
■Product Description
High-performance spark plug that improves both 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, making them high-performance spark plugs.

Specifications
Iridium IX spark plugs offer better ignitability than standard spark plugs, leading to improved fuel efficiency through outstanding combustion efficiency!
Outstanding ignitability with a fine center electrode!
NGK spark plugs were the first in the world to adopt iridium alloy!
Iridium IX spark plugs are high-performance spark plugs with faster flame propagation and less energy loss (quenching effect) compared to standard spark plugs.
Thermo-edge is exclusive to NGK spark plugs!
Maintains high performance because it resists fouling!
A thermo-edge that generates 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 high ignitability of the spark plug.
The fine-diameter 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, stable combustion is always achieved, leading to improved fuel efficiency.
