The Champion N4C spark plug, manufacturer part number 803 and vendor part number N4C, is designed to provide dependable ignition performance for compatible gasoline engines. Its copper core center electrode supports accurate heat-range control, helping promote efficient combustion, consistent starting, and reliable operation across a broad range of driving conditions. This Champion spark plug is a practical replacement for applications requiring the N4C model.
Fitment: Intended for vehicles and equipment that specify a Champion N4C or equivalent 803 spark plug. Always verify the application using the vehicle or equipment manufacturer’s service information before installation, including engine model, ignition requirements, thread specifications, and heat range.
The patented SAC-9 semi-conductor resistor helps suppress electromagnetic interference (EMI) and radio-frequency interference (RFI), supporting cleaner operation of electronic systems and reducing ignition-related signal disruption. The patented Ultraseal™ coated shell provides added protection against rust, helping preserve the plug’s serviceability in demanding operating environments.
