![]() ![]() Running too hot spark plug for given application can result in serious engine damage. If spark plug fouls and starts to misfire, move up one heat range. If uncertain about the heat range, always start with a colder heat range spark plug. Always follow manufacturer spark plug heat range recommendations and as rule of thumb for every +50 to 100 Hp use one-step colder spark plug. For seriously modified applications and/or applications over 500hp colder Brisk spark plug heat ranges should be used. to NGK TR-55, or TR-5), and the Brisk Premium GOR15LGS spark plug (equiv. The actual sequence of most popular spark plug heat ranges is as follows:įor example, the most common Brisk spark plug for a late model Chevy and Ford stock applications is the Brisk Premium GOR17LGS spark plug (equiv. to NGK 10), and the hottest spark plug is 19 (equiv. The letter before the spark plug heat range number designates the spark plug dimension, and the letters after the heat range number designates the spark plug firing tip configuration. Brisk spark plug marking system is customer friendly. All Brisk performance spark plugs (except Racing Iridium) utilize Silver center electrode, because silver is the best thermal and electrical conductor of all metals. For the extreme stress, ultimate power applications, endurance or Rally Racing we offer the Brisk Racing Turbo Evolution spark plugs. ![]() Brisk Racing spark plugs have many unique performance features and optimized diameter spark plug center electrode for lower ignition system requirements ( Brisk Silver Racing spark plugs, Brisk Premium Iridium Racing spark plugs). For applications without sufficient ignition power to run the Brisk Premium LGS spark plug, applications with hard to ignite type of fuel (alcohol, LPG, and other), and/or applications with very high forced induction pressures, Brisk offers Brisk Silver Racing spark plugs, Brisk Premium Iridium Racing spark plugs and Brisk Racing Turbo Evolution spark plugs. The Brisk Premium LGS spark plug is an excellent choice for stock and mild power applications, and high power applications with powerful or upgraded ignition systems (such as MSD). This is important especially in performance applications, where dense environment inside the combustion chamber makes it difficult for a spark discharge to occur. The Brisk Premium LGS spark plugs brings more ignition power inside the combustion chamber and therefore requires the ignition system to be in sound condition. The improvement in efficiency is as beneficial for everyday driver as for professional race application. Brisk Premium LGS spark plugs are for example used as OE (Original Equipment) spark plug in Lamborghini 12 cylinder 1000 hp engines. The Brisk Premium LGS design spark plugs were developed by Brisk research and development center in Italy, in cooperation with Lamborghini. On late model stock vehicles timing advance is controlled automatically by knock-sensor feed back to ECU/PCM. In addition, faster rise in cylinder pressure helps eliminate the need for running excessive timing advance, which generates excessive heat and can strain the engine. This contributes to faster and more complete burn, resulting in increase of mean cylinder pressure of each combustion cycle. Once the ignition process is initiated the flame front can expand in almost all directions, without standard ground electrode restriction. The proprietary design of the Brisk Premium LGS spark plugs provides for maximum spark exposure, and unrestricted access of the air/fuel mixture. The Premium ZC spark plug has a centre electrode with copper core and the Premium ZS has a silver centre electrode.The Brisk Premium LGS spark plugs are designed to maximize the benefit of high power factory ignition systems used on late model vehicles. The Premium ZC/ZS range spark plugs require powerful ignition systems, perfect blending of mixture and utilisation of the engines in the high-rpm zone. The special spark gap protrudes deep into combustion chamber, thanks to which the mixture is perfectly ignited in the combustion chamber. Three sparks in series at one impulse of the ignition system with a possibility of spark-over around the full circumference (360°).Īuxiliary electrodes deposited on insulator tip with special patented technology lend the spark plugs unique properties, particularly the balancing of the individual indicated mean pressures and shift of their average toward the upper limit, which in the final consequence increases engine power. ![]() Spark plugs with two auxiliary electrodes on the surface of the insulator tip.
