DOR15LGS Brisk Spark Plugs Brisk Racing Premium LGS Spark Plugs Brisk Premium LGS spark plug has been developed after two-year cooperation with Lamborghini Morori Marini. Brisk Premium LGS spark plug utilizes extremely long glide-spark & massive integrated side electrode. Massive integrated side electrode ensures superior heat removal from active part of the spark plug even in the most extreme conditions, therefore eliminating electrode burn off seen on conventional spark plugs in race applications. Extremely long glide spark (almost 3mm) protrudes deep into combustion chamber, carries more potential charge & is unshielded by the conventional side ground electrode. The air & fuel mixture is ignited by the Brisk Premium LGS spark plug more spontaneously & flame front spread is unrestricted & more uniform. Spark gap enabling surface flashover (extreme long) with the possibility of spark-over around full circumference 360&176;. 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 & Applications High-Potential Semi-Surface Discharge = MORE POWER Discharge at Point of Richest Misture in 360 Degrees Perimeter Patented Firing Tip Design
- No Indexing Retracted Integrated Ground Electrodes Silver Center Electrode
- Best Thermal & Electrical Conductor Properties of Materials Material Thermal Conductivity W/ (m K) Electrical Conductivity MS/m Silver 407 66 Copper 384 57 Gold 310 45 Iridium 147 18 Platinum 70 10 Nickel 59 10

DR15YS Brisk Spark Plugs Special spark plugs for gas-driven engines LPG combustion has its unique problems. A lot of scientific studies proved already that the use of LPG as alternative fuel for internal combustion engines is advantageous from several points of view. The most important fact is, that engines which use LPG as fuel produce exhaust which is more environmentally friendly than exhaust produced by engines which combust petrol or diesel. At LPG combustion it is generated by 10% up to 25% less of carbon monoxide than at petrol combustion. Nevertheless carbon monoxide has a substantial effect on global warming. With the view to ecology of operations the user are able to calculate the advantages of lower operating costs. LPG combustion has its unique problems, too. More difficult ignitability owing to inhomogeneous gas mixture in combustion chamber is one of them. Increased demand on ignition system voltage & more difficult starting-ability at low temperatures is the consequence. The spark plugs BRISK Silver which are designed specially for gas ignition in LPG-driven engines help to eliminate these problems. Spark plugs BRISK Silver have special shape of spark gap which enable easier access of gases to flashover, silver center electrode with small diameter & electrode gap 0, 55 mm, 0, 7 mm & 0, 9 mm. The voltage demand of spark plug is considerably reduced by silver centre electrode with small diameter along with reduced ground electrode. Replacement interval: max. 30.000 km
- LPG, CNG max. 45.000 km
- for petrol only
