NGK IGR7A-6687 Iridium Spark Plug 6687, One-piece, Double Platinum Type

【NGK IGR7A-6687 Iridium Spark Plug 6687 Integral Type Double Precious Metal Type】
■Product Description
High-performance spark plug that improves both fuel efficiency and acceleration.
Compared to standard spark plugs, Iridium IX plugs offer faster flame propagation and feature a thermo-edge on the insulator tip to improve resistance to plug fouling, making them high-performance spark plugs.

Specifications
Iridium IX plugs offer superior ignition compared to standard plugs, leading to improved fuel efficiency due to excellent combustion efficiency!
Excellent ignitability with a fine-tipped center electrode!
NGK Spark Plugs were the first in the world to adopt an iridium alloy!
Compared to standard plugs, Iridium IX plugs are high-performance plugs with faster flame propagation and less energy loss (quenching effect).
Thermo-edge is exclusive to NGK Spark Plugs!
High performance lasts longer because it's resistant to fouling!
The thermo-edge, where micro-discharges occur, is designed into the insulator tip. This micro-discharge burns off carbon that adheres to the insulator during prolonged low-speed driving, constantly maintaining high ignition performance of the plug.
The fine-diameter iridium alloy center electrode improves electric field strength, generating a stronger spark 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.
