NGK PMR-9B Spark Plug - 4717

Upgrade your engine's performance with this high-quality NGK Spark Plug. Designed for optimal ignition and longevity, this spark plug ensures efficient combustion and reliable starts. Experience enhanced engine response and fuel efficiency with NGK's trusted technology.

Description

The NGK Spark Plug delivers superior anti-corrosion and anti-seizing properties thanks to its trivalent metal plating. The pure alumina silicate ceramic insulator provides exceptional strength and heat transfer, preventing overheating and ensuring consistent performance. Triple seals are incorporated to eliminate leakage, maintaining optimal compression and combustion. Corrugated ribs effectively prevent flashover, ensuring a reliable spark even under demanding conditions. Furthermore, the copper core efficiently dissipates heat, preventing pre-ignition and extending the lifespan of the plug. This resistor-type spark plug with a fine wire platinum electrode delivers enhanced ignitability and reduced voltage requirement, while minimizing radio frequency interference. Enjoy a smoother running engine, improved fuel economy, and extended spark plug life.
