Product Details

The NGK 5866 BKR5E-11 is a standard copper core spark plug designed to deliver reliable ignition performance for a wide range of automotive applications. As an OE-quality replacement plug, it meets original equipment specifications for durability and operational efficiency.

Key Features:

  • Copper core electrode for superior heat dissipation and conductivity
  • Trivalent metal plating for enhanced corrosion resistance
  • Solid terminal design for reliable electrical connection
  • Cold heat range for performance applications
  • 11mm thread reach with 16mm hex size
  • Pre-gapped at 1.1mm (0.043 inches) for quick installation

NGK's precision manufacturing ensures consistent electrode spacing and reliable spark formation. The BKR5E-11 features a projected insulator nose design that helps prevent fouling in demanding conditions while maintaining optimal combustion chamber temperatures.

This standard spark plug is engineered for applications requiring a colder heat range than conventional plugs, making it suitable for modified or high-performance engines. The copper core provides excellent thermal conductivity to prevent pre-ignition and engine damage.
