The purpose of the NGK Standard Spark Plug is to improve the vehicle's performance. It is made of corrosion-resistant and abrasion-resistant material. The spark plug insulators are 99 percent pure alumina silicate, which allows for longer insulator noses and less fouling. A triple gasket sealing method prevents gasoline from leaking with this spark plug. There's also a solid copper core for better heat dissipation and conductivity. This spark plug contains a glass and carbon resistor that burned for best performance and longevity. Corrugated ribs prevent flashover, while cold-rolled threads avoid cylinder head damage. NGK produces plugs for nearly every application and riding style. Key Features: Anti-corrosion and anti-seizing capabilities with trivalent metal plating. Flashover is avoided via corrugated ribs. Superior strength and heat transfer using pure alumina silicate ceramic insulator. The heat is dissipated more effectively with a copper core. Leakage is kept to a minimum, thanks to three seals. It gives more power and performance to the engines. Product Details: SKU: 86-7331 UPC: 087295073315 Weight: 0.15 LBS Brand: Autowares Core Material: Copper Top Material Type: Ceramic
