Brisk SKU  -  EOR15LGS 

Brisk MPN  -  3143

Heat Rating  -  15

Brisk Premium Racing Spark Plugs LGS have unique multi earth electrode design and a silver core giving an outstanding performance in igniting over reach mixture associated with tuned performance engines. 

As the arcing occurs around the 360 degrees and is not mixture dependant a bigger gap is used at lower voltage levels thus increasing greatly an ignition surface area.

Silver metal is the single best material for a spark plugs core electrode, as it can dissipate heat fast, resulting in overall lower spark plug temperature and more powerful spark. The stronger the spark the faster and better the flame front, couple this to the multi earth electrode design and the dependants on a homogeneous mixture needed to be found around specific point, as it is the case on single earth, hook electrode. is not required. 

Our LGS range works well with most aftermarket and OEM ignition systems form simple coil and distributor through electronic ignition and powerful direct ignition systems found on modern port and direct injection performance engines.
