Installation Notes
Verify thread diameter, reach, seat type, heat range, and terminal style before installation. Champion 516 uses a removable nut terminal and a pre-gap of 0.025 in, so confirm the engine specification before tightening the plug to the correct torque. For vehicle and equipment searches such as Champion 516 spark plug for tractor ignition or industrial engine tune-up parts, match the plug dimensions to the original service part before use.
Compatible With applications calling for Champion 516, Champion Copper Plus 516, or D16-style agricultural spark plugs. Vehicle-specific fitment data was not provided, so confirm by engine specification rather than make/model lookup. For make/model searches such as Ford tractor or John Deere equipment, use the original plug dimensions and heat range to verify application.
Quality Assurance
Champion states that its industrial and agricultural spark plugs are supported by global engineering from Federal-Mogul. The Copper Plus line is built around durable electrode materials and service-focused construction for demanding operating conditions.
