NGK DILKAR7Q8-91899 Iridium Spark Plug 91899 Integrated, Double Precious Metal Type

【NGK DILKAR7Q8-91899 Iridium Plug 91899 Integrated Type, Double Precious Metal Type】
■Product Description
High-performance plug that improves both fuel efficiency and acceleration.
Iridium IX plugs are high-performance plugs that offer faster flame propagation compared to standard plugs and incorporate a thermo edge at the tip of the insulator to improve resistance to plug fouling.

Specifications
Iridium IX plugs offer superior ignitability compared to standard plugs, leading to improved fuel efficiency thanks to excellent combustion efficiency!
Excellent ignitability with a fine-wire center electrode!
NGK Spark Plugs was the first in the world to adopt an iridium alloy!
Iridium IX plugs are high-performance plugs with faster flame propagation and less energy loss (quenching effect) compared to standard plugs.
The thermo edge is exclusive to NGK spark plugs!
Resistant to fouling, maintaining high performance!
The thermo edge, which generates micro-discharges, is designed at the tip of the insulator. It burns off carbon deposits on the insulator during prolonged low-speed driving with micro-discharges, constantly maintaining high ignitability.
The fine-diameter iridium alloy center electrode improves electric field strength, generating a stronger spark at a lower voltage.
The spark concentrates at the tip of the center electrode, ensuring stable combustion and leading to improved fuel efficiency.
