Advantages of Brisk High Performance & Racing Spark Plugs
Unique And Patented High Performance Spark Plug Designs

Higher output, better throttle response and acceleration are achieved through better fuel energy utilization. This in turn also lowers the exhaust emission.

Completely New and Patented High Performance Spark Plug Gap Configurations

Brisk's design provides an unrestricted and more spontaneous spread of the flame front which is achieved by:

Retracted ground electrode- Unlike conventional spark plugs, where the discharge is constrained by the ground electrode, Brisk Premium Spark Plugs utilize a design where the ground electrode is retracted so the spark discharge occurs at the very tip of the spark plug.

The ground electrode design of the traditional spark plug restricts the natural spherical expansion pattern of the flame front Brisk Premium Spark Plugs utilize surface spark discharge along with retracted ground electrode designed to ensure maximum spark exposure and unrestricted flame front propagation

Utilizing hotter semi-surface spark discharge- It is easier (takes less energy) for a spark to glide along the surface of the insulator than to break through the air gap. Brisk Premium Spark Plugs take advantage of this feature in its design. Almost 2/3 of the spark travel between the electrodes is along the surface of the insulator. The length of the spark discharge is maximized with only a slight increase in the required supplied ignition energy. The higher voltage buildup at the center electrode before the spark-over results in delivering more spark energy into the combustion chamber. However, this spark plug requires a sound ignition system (in good condition) for proper operation.

Utilizing a special ground electrode design- The spark discharge can occur in almost 360 degree perimeter at the place with the most optimal air fuel composition; which is where the ionization of the molecule is most easily achieved. This special feature ensures that the spark occurs at the best possible place for ignition, unlike in the conventional spark plug design where the spark always occurs in the same confined place. Since the air fuel mixture inside the combustion chamber is not homogenous (has different concentration at different places) this results in faster and better ignition of each ignition cycle. In addition, there is no need for indexing of the spark plugs since the plug is symmetrical and there is no ground electrode restricting the access of the air fuel mixture.
Spark Plug Gap is Close to the Center of the Combustion Chamber

Shifting the spark gap deeper inside the combustion chamber provides better access of the air fuel mixture to the point of ignition. Since the flame front propagates evenly in all directions the best place for ignition is in the center of the combustion chamber. The compact design of the spark gap minimizes turbulence and therefore increases the volumetric flow.
Spark Plug Integrated High Performance Ground Electrode

The massive ground electrode is the integrated part of the spark plug shell which provides superior heat removal from the active part of the spark plug, improving the resistance to pre-ignition and electrode burn-off.
