NGK IZFR6K11-6994 Iridium Spark Plug 6994 Integrated, Dual Precious Metal Type

【NGK IZFR6K11-6994 Iridium Plug 6994 One-piece, Double Precious Metal Type】
■Product Description
High-performance plug that improves both fuel efficiency and acceleration.
Iridium IX plugs are high-performance plugs that achieve faster flame propagation compared to standard plugs, and also feature a thermo edge at the tip of the insulator to improve plug fouling.

Specifications
Iridium IX plugs offer better ignitability than standard plugs and excellent fuel efficiency for improved fuel economy!
Excellent ignitability with a fine center electrode!
NGK Spark Plugs were the first in the world to adopt an iridium alloy!
Iridium IX plugs are high-performance plugs that have faster flame propagation and less energy loss (quenching effect) compared to standard plugs.
The thermo edge is unique to NGK Spark Plugs!
High performance lasts longer because it resists fouling!
The thermo edge, which creates micro-discharges, is designed at the tip of the insulator. It burns off carbon that adheres to the insulator during long periods of low-speed driving with micro-discharges, constantly maintaining high ignitability of the plug.
The fine-diameter iridium alloy center electrode improves electric field strength and generates stronger sparks at lower voltages.
Since the spark is concentrated at the tip of the center electrode, stable combustion is always achieved, leading to improved fuel efficiency.
