NGK IMR8C-9H-3653 Iridium Spark Plug 3653 Screw Type Double Precious Metal Type

【NGK IMR8C-9H-3653 Iridium Plug 3653 Screw 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, compared to standard plugs, have a faster combustion spread and feature a thermo edge at the tip of the insulator to improve plug fouling.

Specifications
Iridium IX plugs have better ignitability compared to standard plugs, leading to improved fuel efficiency due to excellent fuel efficiency!
Excellent ignitability with an ultra-fine center electrode!
NGK spark plugs were the first in the world to adopt an iridium alloy!
Iridium IX plugs are high-performance plugs that, compared to standard plugs, have a faster flame propagation and less energy loss (quenching effect).
Only NGK spark plugs have a thermo edge!
Long-lasting high performance because it resists fouling!
A thermo edge, where minute discharges occur, is designed at the tip of the insulator. It burns off carbon adhering to the insulator during prolonged low-speed driving with minute discharges, consistently maintaining high ignitability of the plug.
The ultra-fine 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.
