The NGK Spark Plugs CPR9EA-9 Spark Plug is designed to deliver dependable ignition performance, efficient combustion, and long service life in compatible powersports and small-engine applications. Manufactured by NGK Spark Plugs, this spark plug uses a copper-core center electrode to help transfer heat away from the firing end, supporting consistent operation across a range of engine conditions. The model is CPR9EA-9, and the manufacturer and vendor part number is 2308.
Its pure alumina silicate ceramic insulator provides high strength, excellent insulation, and efficient heat transfer. Trivalent metal plating helps resist corrosion and reduces the likelihood of thread galling or seizing during installation and removal. Triple sealing provides enhanced protection against combustion-gas leakage, while the corrugated insulator ribs help prevent flashover for reliable ignition performance.
Before installation, verify that the CPR9EA-9 model and 2308 part number match the vehicle or equipment manufacturer’s application requirements, including heat range, reach, thread specification, and recommended gap. This NGK Spark Plugs replacement spark plug is intended for compatible engines using the CPR9EA-9 configuration and should be installed according to the manufacturer’s service instructions. Proper fitment and correct torque are essential for dependable performance and safe operation.
