NGK SIMR8A9-91064 Iridium Spark Plug 91064 Screw Type Double Precious Metal

【NGK SIMR8A9-91064 Iridium Spark Plug 91064 Threaded, Double Precious Metal Type】
■Product Description
High-performance spark plug that improves both fuel economy 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 resistance to fouling, making them high-performance spark plugs.

Specifications
Iridium IX spark plugs offer better ignitability than standard spark plugs, leading to improved fuel efficiency thanks to excellent combustion efficiency!
Excellent ignitability with a fine center electrode!
NGK spark plugs were the first in the world to adopt an iridium alloy!
Iridium IX spark plugs are high-performance spark plugs that offer faster flame propagation and less energy loss (quenching effect) compared to standard spark plugs.
The thermo-edge is exclusive to NGK spark plugs!
High performance is maintained because it resists fouling!
The thermo-edge, where micro-discharge occurs, is designed at the tip of the insulator. It burns off carbon adhering to the insulator during prolonged low-speed driving with micro-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 economy.
