Brisk Racing Spark Plugs are engineered for the Yamaha MT-09 engine used in Legend Car racing, delivering strong ignitability, consistent combustion, and dependable performance under demanding track conditions. Featuring a smaller-diameter silver center electrode and a conventional open-hook ground electrode, these plugs are designed to support clean, efficient spark delivery across the RPM range.
 
Silver is one of the best materials available for a spark plug center electrode due to its excellent thermal conductivity. By dissipating heat quickly, it helps lower overall plug temperature while promoting a strong, stable spark. In a high-revving Legend Car MT-09 engine, that means improved flame travel, smooth combustion, and reliable performance when it matters most.
 
Built for racing applications, Brisk Silver Racing Spark Plugs are a great option for competitors looking for a plug that can keep up with the demands of the MT-09 platform. They are compatible with OEM and most aftermarket ignition systems, making them a proven choice for Legend Car racers focused on performance, consistency, and durability.
