BRISK SPARK PLUGS
FOR TUNING AND RACE APPLICATIONS

• Forced induction applications such as supercharged and turbocharged
• Nitrous Oxide applications

Tuning                  

Car designers have to design vehicles for mass production. They are limited by continuous reductions to production costs and extending service inspection intervals. This all results in cars design where, performance and utility features are acceptable for most drivers.
There are some people, however, who are not satisfied with the uniformity of mass-produced vehicles and want to apply some degree of uniqueness. These efforts have led to an activity that is called "tuning" in the automobile industry. Tuning involves modification of appearance and shape of the body, sound of the exhaust pipe and often also engine power. There are many options for increasing engine power. One of the easiest methods is the use of a special spark plug.

Racing

BRISK manufactures special Sport Racing spark plugs for high-efficiency engines in racing cars; they have colder thermal values such as 12, 10 and 08. They are adapted to high temperatures in the combustion chamber, vibrations and, in the -T and Turbo Racing version (closer electrode distance), also high- supercharged pressures. It is known fact that longer spark discharge supplies more ignition energy into the combustion chamber, however increasing compression ratio, installation or increase of boost pressure of a supercharger or turbo significantly increases voltage requirements of your ignition system. Your stock ignition system might not be capable of supplying required voltage to ignite dense air-fuel mixture in the combustion chamber. In such cases it is necessary to upgrade your ignition system (such as MSD ignition ) or use of a -T or Turbo Racing version of a plug with a closer electrode distance.

Increase in compression, forced induction such as blowers and turbo, Nitrous Oxide and other power adders also requires a use of a colder heat range spark plug. If unsure of a proper thermal value (heat range) it is safer to start with a coldest spark plug and work your way up. If the heat range is too cold spark plug will not reach it's required operating temperature and the spark plug will foul out. The result will be a misfire instead of possible engine damage from detonation or pre-ignition caused by selecting spark plug with too high thermal value (heat range).

Equipment for racing cars is highly individualized and requires much experience in the choice of the best thermal value. Compression, boost pressure, air-fuel ratio, timing and other variables plays major role in selection of an appropriate thermal value (heat range) of a spark plug. Wrong decision can lead to serious engine damage. Please consult unclear cases with an expert or the producer. Any damages, implied or consequential caused by improper choice of spark plug cannot be claimed against the importer or producer of the spark plug.
