Completely New Spark Gap Shape
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 utilise a design where the ground electrode is retracted so the spark discharge occurs at the very tip of the spark plug.

Utilising 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 maximised with only a slight increase in the required supplied ignition energy. The higher voltage buildup at the centre 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. 
 
Utilising 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 ionisation 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 concentrations 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 Gap Deep in 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 centre of the combustion chamber. The compact design of the spark gap minimises turbulence and therefore increases the volumetric flow.

Integrated 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.
