BRISK Premium DOR12LGS Spark Plug 14mm thread, 3/4″(19mm) reach, 5/8′(16mm) hex, gasket seat, resistor, LGS Lamborghini semi-surface firing tip design, retracted integrated ground electrodes, silver center electrode. Please visit PLUG MODELS – LGS for more firing tip configuration information.

Spark gap enabling surface flashover (extreme long) with the possibility of spark-over around full circumference 360. Ignition spark will jump always at point of highest fuel concentration. Substantially higher flame propagation rate in the initial phase of flame propagation in the combustion chamber enables superior fuel energy utilization. The combustion velocity in conjunction with knock sensor assures engine-power increase. The spark gap of spark plugs BRISK PREMIUM “LGS” is protruded deep into combustion chamber.

KEY BENEFITS AND APPLICATIONS

• High-Potential Semi-Surface Discharge = MORE POWER

• Discharge at Point of Richest Moisture in 360 Degrees Perimeter

• Patented Firing Tip Design – No Indexing

• Retracted Integrated Ground Electrodes

• Silver Center Electrode – Best Thermal and Electrical Conductor
