Wholly new BRISK Premium LGS spark plug employs the principle of the revolutionary spark plugs BRISK Premium ZS and TXS. Extremely long sliding spark provides perfect ignition of the mixture in the engine cylinder. Patented principle of the circular spark gap along with the spark reaching deep into the combustion chamber ensure that the spark flashes wholly freely along the whole perimeter (360 degree), in a point with the highest concentration of fuel. This feature provides better uniformity of ignition of individual engine cycles and fast burning.
