Product Details

The Champion RN14YC (Part #405) is a Copper Plus spark plug designed to deliver dependable ignition performance across a wide range of gasoline-powered engines. Part of Champion's trusted Copper Plus line, this plug features a copper core center electrode that enhances electrical conductivity and improves heat dissipation for consistent firing and long service life.

Key Features:

  • Copper Core Electrode: Provides superior conductivity and efficient heat transfer to maintain optimal operating temperature
  • Nickel Alloy Electrodes: Center and ground electrodes resist corrosion and wear for extended plug life
  • Ribbed Insulator: Helps prevent flashover and ensures reliable high-voltage performance
  • Pre-Set Gap: Factory-gapped for easy installation and consistent spark
  • OEM-Style Fit: Designed to meet or exceed original equipment specifications
  • Thread Size: 14mm with a 5/8 in. (16mm) hex, standard reach

The Champion RN14YC uses the industry-standard resistor-type construction to suppress ignition noise and protect sensitive electronic systems. This plug is sold individually and is an excellent choice for maintenance replacements in a broad range of passenger cars, light trucks, and SUVs that call for a standard copper spark plug.
