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. Please get in touch using one of the options on our 'contact us' page.The Brisk Premium LGS spark plugs are designed to maximize the benefit of high power factory ignition systems used on late model vehicles. Need a spark plugs for your engine but you are unsure of what to get, no problem! Our trained and knowledgeable staff will be able to assist you and find the right product for your application. Lower boost Turbocharged or Supercharged engines FeaturesĬontinuous spark gap over entire circumference 360°.Ĭars with unleaded, race or Nitrous fuel. The ignition arc gives off a sparkle like effect all around the center core and laser deposited rings on circumference of ceramic insulator. The 360 degree arc design can occur on a minimum of 3 points at once, even very rich mixture found in race engine under heavy load. This manufacturing system gives far superior utilization of fuel energy and reduction in fuel consumption of new and older engines.īrisk ZS ZC racing spark plugs are the very latest in ignition technology pushing the boundaries of spark plug design to the limit. Made out of silver the center core is isolated by a laser deposited ceramic insulator. GR12ZC Brisk Premium Racing Spark Plugs ZC ZSīrisk premium racing spark plugs are a multi spark exposed center core and 360 degree earth electrode design.
