NGK ILZFR6C-11K-90428 Iridium Spark Plug 90428 - One-Piece, Double Precious Metal Type

[NGK ILZFR6C-11K-90428 Iridium Spark Plug 90428 One-piece, Dual Precious Metal Type]
■Product Description
High-performance spark plugs that improve both fuel efficiency and acceleration.
Compared to standard spark plugs, Iridium IX spark plugs ignite combustion more rapidly, and are high-performance spark plugs that also feature a thermo edge at the tip of the insulator to improve plug fouling resistance.

Specifications
Compared to standard spark plugs, Iridium IX spark plugs offer excellent ignitability and outstanding fuel efficiency, leading to improved fuel economy!
Outstanding ignitability with a fine-wire center electrode!
NGK Spark Plugs was the first in the world to adopt an iridium alloy!
Compared to standard spark plugs, Iridium IX spark plugs offer faster flame propagation and less energy loss (quenching effect), making them high-performance spark plugs.
Thermo edge is exclusive to NGK Spark Plugs!
High performance lasts longer because it's resistant to fouling!
The thermo edge, which generates microscopic discharges, is designed at the tip of the insulator. It burns off carbon adhering to the insulator during long periods of low-speed driving with microscopic discharges, constantly maintaining high ignition performance of the spark plug.
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, stable combustion is always achieved, leading to improved fuel efficiency.
