NGK Iridium Spark Plug SILMAR8C9

NGK is the brand leader in the UK spark plug market and is the world's biggest supplier to most motorcycle and car manufacturers. Each and every one of their products is designed to meet the most rigorous standards and are the professionals' choice due to their quality and technical excellence. Their plugs can be found in use by teams in F1, WRC and MotoGP. Put simply, NGK genuine spark plugs are the workhorse at the heart of smooth-running engines around the world.

The NGK Standard Spark Plug is constructed from durable material that is corrosion and abrasion-resistant. The spark plug insulators are made of 99 per cent pure alumina silicate, allowing for longer insulator noses for reduced fouling. This spark plug features a triple gasket sealing process that eliminates fuel leakage. It also includes a solid copper core that provides superior heat dissipation and conductivity. The spark plug's resistor is manufactured from a mixture of glass and carbon, which is fired to ensure superior performance and durability. It has corrugated ribs that prevent flashover and cold rolled threads to inhibit damage to the cylinder head.

Key Features:

  • Superior materials - Many use precious metals such as platinum or gold/palladium for greater durability and lower voltage requirements
  • Electrode configurations - Fine-wire centre electrodes provide better sparking and enhanced ignitability. Fine-wire ground electrodes further improve the ignitability of the plug
  • Insulator configurations - Special configurations are used for the insulator noses to improve throttle response
  • Suitable for car, motorcycle and garden equipment applications. Made in Japan
