NGK BKR8EIX Iridium IX Spark Plug

The NGK BKR8EIX Iridium IX Spark Plug is designed to deliver high-performance ignition with a 0.6mm iridium center electrode for exceptional ignitability, sharper throttle response, and improved fuel efficiency. Its iridium alloy provides longevity, while a taper-cut ground electrode minimizes the quenching effect to promote a clearer path for ignition and a more complete burn. The plug features trivalent metal plating for anti-corrosion and anti-seizing protection and corrugated ribs on the insulator to prevent flashover, supporting reliability under demanding conditions. With a colder heat range of 8, it is intended for modified, turbocharged, or high-compression engines that generate more heat than stock life. This design aims to maximize engine potential by delivering focused, efficient sparks and durable performance across extended use.
