The NGK BR6S is a standard nickel spark plug built for reliable ignition performance in Chevy, GMC, and Chrysler engines used in marine and industrial applications. It features a solid copper core for superior heat dissipation, strong conductivity, and a broad heat range, keeping combustion consistent across a wide range of operating conditions. The plug is treated with corrosion-resistant plating, which makes installation and removal easier and helps prevent thread seizing over time.

The BR6S uses a standard ground electrode configuration with a nickel ground electrode and a nickel center electrode tip over a copper core center electrode. It has a 13/16 inch hex size and ships pre-gapped to.028 inch, with an electrical resistance of 5000 ohms. As an NGK Standard plug, it is engineered to OE specifications, making it a straightforward replacement for engines that call for this plug type.
