The Brisk USA DR15ZC Multi-Spark Spark Plug is built to create three simultaneous sparks using a patented electrode design—no special ignition upgrades required. By eliminating spark “shrouding” (blocking), the sparks have more direct exposure to the air/fuel mix for faster, more complete flame propagation.

That cleaner, more consistent burn can translate to stronger throttle response, improved power, and fewer imperfect combustion cycles—helping reduce unburnt fuel and improving efficiency. It’s a solid fit for high-performance street and racing setups, especially engines with precise fueling or mild boost/power adders.

Multi-spark plugs increase engine power
More horsepower, torque, faster acceleration and response
Maximum spark exposure; better use of available energy
Silver center electrode—the best conductor of any metal
