The NGK Spark Plugs CR8EH-9 Spark Plug is designed to deliver dependable ignition performance, consistent combustion, and long service life in compatible powersports and small-engine applications. This NGK spark plug uses a copper core to help transfer heat away from the firing end, supporting stable operating temperatures and reliable performance under demanding conditions.
Its pure alumina silicate ceramic insulator provides high strength and efficient heat transfer, while the trivalent metal plating helps resist corrosion and reduces the risk of seizing during installation or removal. Triple seals help prevent gas and combustion leakage, and corrugated insulator ribs reduce the potential for flashover to support dependable ignition.
Use the NGK CR8EH-9 for applications that specify this model and heat range. Verify vehicle or equipment fitment, thread specifications, and manufacturer recommendations before installation. This product is manufactured by NGK Spark Plugs and is identified by manufacturer part number 5666 and vendor part number CR8EH9.
