Product Details
Champion Copper Plus 801 is engineered around a copper core design that helps carry current efficiently while controlling operating temperature at the plug tip. The nickel electrode materials support stable spark delivery and normal wear in ignition systems that call for a non-resistor plug with a flat seat and N3C plug type. For Porsche 911 owners restoring or maintaining older ignition systems, this plug matches the listed fitment for 1974, 1976-1977, and 1981-1989 models.
This part number, 801, is a practical choice when you need a Champion spark plug with the specified reach, thread size, and heat range for the application. It is also cross-referenced to NGK 4055 and Autolite 1111 for the same application.
What It Helps Address
- Hard starting caused by worn or incorrect spark plugs
- Misfire from weak or inconsistent spark delivery
- Rough idle related to plug wear or incorrect heat range
- Ignition performance issues in non-resistor plug applications
- Service replacement needs for Porsche 911 ignition maintenance
Installation Notes and Tips
Verify the plug type, seat style, thread diameter, reach, and heat range before installation. For Porsche 911 fitments, confirm the required gap specification in the vehicle service information; listed notes include 0.024 in for 1976-1977 and 1981-1989 models, and 0.028 in for 1974 models. Use the correct torque procedure for the cylinder head material and inspect the ignition wire terminal style before installation.
Quality Assurance
Champion Copper Plus plugs are built around a copper-core design for conductivity and heat control, with nickel electrode materials selected for dependable service life in the specified application.
