NGK BR7EFS Spark Plug – Stock No. 1094
The NGK BR7EFS is a resistor spark plug designed for reliable ignition under sustained load and higher temperatures. It uses a copper core for better heat control and a durable nickel alloy electrode for long service life. Ideal where a colder heat range is needed to help manage knock and pre-ignition in tuned or hard?worked engines.
Use this plug where the engine manufacturer specifies a 14 mm thread, 19 mm reach, tapered seat, and NGK heat range 7. If unsure, use our vehicle lookup or check the Vehicle Fitment tab.
