NGK DILZKAR6A11-91691 Iridium Spark Plug 91691 One-piece, Double Precious Metal Type

【NGK DILZKAR6A11-91691 Iridium Spark Plug 91691 Integrated Double Precious Metal Type】
■Product Description
High-performance spark plug for improved 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 resistance to 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 thanks to outstanding combustion efficiency!
Excellent ignitability with a super-fine center electrode!
NGK Spark Plugs was the first in the world to use iridium alloy!
Compared to standard spark plugs, Iridium IX spark plugs have 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 resists fouling!
The thermo-edge, where micro-discharges occur, is designed at the tip of the insulator. It burns off carbon deposits on the insulator from 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 efficiency.
