NGK KR8BI-4347 Iridium Spark Plug 4347 Integrated Type, Single Precious Metal

【NGK KR8BI-4347 Iridium Spark Plug 4347, One-piece, Semi-precious metal type】
■Product Description
High-performance spark plug that improves both fuel efficiency and acceleration.
Iridium IX spark plugs offer faster flame propagation than conventional spark plugs and feature a thermo-edge on the insulator tip to improve plug fouling, making them high-performance spark plugs.

Specifications
Iridium IX spark plugs offer better ignitability than conventional spark plugs, leading to improved fuel efficiency thanks to excellent fuel efficiency!
Excellent ignitability with a super fine center electrode!
NGK Spark Plugs was 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 conventional spark plugs.
Thermo-edge is exclusive to NGK Spark Plugs!
High performance is maintained because it resists fouling!
The thermo-edge, which generates micro-discharges, is designed into the tip of the insulator. It burns off carbon deposited on the insulator during long periods of low-speed driving with micro-discharges, maintaining consistently high ignition performance of the spark plug.
The ultra-fine iridium alloy center electrode improves electric field strength and generates a stronger spark at lower voltage.
Since the spark is concentrated at the tip of the center electrode, stable combustion is always achieved, leading to improved fuel efficiency.
