Part #: BKR7EKC-N

NGK Multi-Ground Electrode where "N" stands for Nickle (requires a 16mm socket)

The Spark Plug improves ignition capabilities and is less sensitive to increased voltage requirements due to
gap growth.

Optional BOSCH substitute is FR6KDEO or FR6KDC+ with Ytrium Center Electrode

Application Table
NOTE: A plug with a low heat range number is a cold plug that quickly dissipates heat to the engine block and cooling system, while a high heat range is a hot plug that retains heat. By properly selecting the heat range of the plug, it ensures that the plug will operate between the plug’s designed operating range of 500-900 degrees Celsius. In this range, the spark plug will be self-cleaning, yet will not be hot enough to pre-ignite the air/fuel mixture

  • Revolutionary surface air gap firing technology featuring four yttrium-enhanced ground electrodes delivers the longest, most powerful spark for ultimate engine performance
  • Four yttrium-enhanced ground electrodes provide optimum access to the air/fuel mixture for the most efficient combustion, plus the yttrium alloy ground electrodes reduce gap wear and oxidation for extended performance life
  • Electrode gap is factory set to provide ease of installation - never requires adjustment /Never requires gapping, the electrode gap is factory-set and never requires adjustment
  • Provides ease of installation - never requires adjustment
  • Designed to specific manufacturer ignition requirements, NGK's Multi-Ground plugs maintain all the features of their standard plugs, including:
-Corrugated Ribs to Prevent Flashover
-Pure Alumina Silicate Ceramic Insulator, Providing Superior Strength and Better Heat Transfer
-Copper Core to Aid in Heat Removal
-Triple Seals to Prevent Leakage
