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 whose design, 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; their thermal values are 12, 10 and 08. They are adapted to high temperatures in the combustion chamber, vibrations and, in the Turbo Racing version, also high supercharged pressures.
Equipment for racing cars is highly individualized and requires much experience in the choice of the best thermal value. A wrong decision can lead to a seriously damaged engine. Please consult unclear cases with the producer. Damage caused by improper choice of spark-plugs cannot be claimed against the producer of the spark-plug.

To comply with this global trend, BRISK Tábor a.s. offers specifically manufactured spark-plugs suitable for this market. Their names are BRISK PREMIUM RACING and BRISK EXTRA TURBO RACING..

Advantages of BRISK spark-plugs intended for racing and tuning:

	Completely new spark-gap shape
	Higher output
	Better acceleration
	Better fuel energy utilization

Spark plugs PREMIUM "LGS"

	Completely new spark gap shape
	Suitable for TUNING and RACING
	Higher performance
	Better acceleration
	Better utilization of fuel energy
	Possible discharge along the whole perimeter of the isolator top
	Shifted spark gap
	Balancing of individual engine cycles

Excellent utilization of fuel energy allows increased engine power!

The round spark gap with extremely long surface spark discharge uses the possibility of spark-over along the whole perimeter of 360^o. The spark always flashes in the place with the highest fuel concentration; the spark gap in the Brisk Premium "LGS" spark-plugs protrudes deep into the combustion chamber. The significantly higher combustion velocity in the initial spread of the flame in the combustion chamber allows excellent utilization of fuel energy, which provides higher engine power.

PREMIUM LGS

Conventional spark-plugs

PREMIUM ZC/ZS spark plugs

Multispark-plugs increase engine power.
Two auxiliary electrodes attached to the top of the isolator use special patented technology allowing simultaneous spark-over on two surfaces and one airborne spark for each ignition system pulse. Each spark can flash along the whole perimeter of the auxiliary electrode (360^o). The spark gap is deep inside the combustion chamber and improves the initial spread of flame front. The number of sparks and sufficient distance between them decreases the likelihood of an imperfect mixture ignition in the combustion chamber and increases combustion velocity and engine power.

PREMIUM TXS spark plugs

Multispark-plugs increase engine power.
An auxiliary electrode attached to the top of the isolator use special patented technology and three short electrodes on the casing allow simultaneous spark-over of one surface and one airborne spark for each ignition system pulse. The surface spark can flash along the whole perimeter of the auxiliary electrode (360^o), The airborne spark can flash to one of the three external electrodes. The spark gap is deep inside the combustion chamber and improves the initial spread of flame front. The doubling of sparks decreases the likelihood of an imperfect mixture ignition and increases engine power.

Advantages of PREMIUM spark-plugs:

	Increased engine power
	Improved acceleration
	Reduced emission pollutants in exhaust gases
	Reduced fuel consumption

Premium spark-plugs can reduce the number of imperfectly ignited cycles in the combustion chamber of a spark-ignition engine, which usually occur in transient modes.A better combustion mixture can improve engine operation, lead to better utilization of energy contained in fuel and reduce the amount of emission pollutants.
