NGK IFR6B-6507 Iridium Spark Plug 6507 Integrated Precious Metal Type

【NGK IFR6B-6507 Iridium Spark Plug 6507 One-piece, Dual Precious Metal Type】
■Product Description
High-performance spark plug that improves both fuel economy and acceleration
Iridium IX spark plugs have a faster flame propagation compared to standard spark plugs, and feature a thermo edge at the tip of the insulator, making them high-performance spark plugs with improved resistance to fouling.

Specifications
Iridium IX spark plugs improve fuel efficiency with better ignitability and outstanding fuel economy compared to standard spark plugs!
Excellent ignitability with a fine-tipped 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 have faster flame propagation and less energy loss (quenching effect) compared to standard spark plugs.
Only NGK Spark Plugs feature a thermo edge!
High performance lasts longer because it's resistant to fouling!
A thermo edge, which generates minute discharges, is designed at the tip of the insulator. This burns off carbon that has accumulated on the insulator during long periods of low-speed driving with minute discharges, consistently maintaining the plug's high ignition performance.
The fine-tipped 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.
