NGK DILKAR7M8-90288 Iridium Spark Plug 90288 One-Piece Double Precious Metal Type

【NGK DILKAR7M8-90288 Iridium Spark Plug 90288 Integrated Double Precious Metal Type】
■Product Description
High-performance spark plug that improves both fuel efficiency and acceleration
Iridium IX plugs offer faster flame propagation compared to standard plugs, 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 better ignitability and excellent fuel efficiency compared to standard plugs, leading to improved fuel economy!
Excellent ignitability with a fine-wire center electrode!
NGK Spark Plugs was the first in the world to adopt iridium alloy!
Iridium IX plugs are high-performance spark plugs that offer faster flame propagation and less energy loss (quenching effect) compared to standard plugs.
Thermo edge is exclusive to NGK spark plugs!
Maintains high performance 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 prolonged low-speed driving with micro-discharges, consistently maintaining high ignition performance of the spark plug.
The fine-wire iridium alloy center electrode improves electric field strength, generating 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.
