Wide range spark plugs with centre electrode and platinum contact. Perfect ignition of air/fuel mixture. Extended replacement interval.

!!! Replacement interval: as recommended by the engine manufacturer / maximum see table below.

The platinum on the centre electrode ensures stability of electrode distance over a very long time. The small diameter of electrode tip does not prevent propagation of the flame front in the combustion chamber and contributes to increase in engine power. This also suppresses the quenching effect during cold starts.

Product range comprising modified spark plugs of the SUPER, EXTRA and PLATIN product ranges. The composition of the sales range ensures deployment in most of the modern vehicles on the market.
The spark plugs derived from the Super product range have one ground electrode in the shape of the letter A and centre electrode from yttrium alloy. The spark plugs derived from the EXTRA product range have a centre electrode from yttrium alloy. The A-LINE product range also includes types with platinum centre electrode from the PLATIN product range.

Unique spark plug with auxiliary electrode at insulator tip created using patented laser application technology.

!!! Replacement interval: as recommended by the engine manufacturer / maximum see table below.

Application of the latest Brisk ?patented? technology and knowledge of engine managements transformed into Premium EVO spark plug series. Especially better utilisation of fuel energy, reduction of specific fuel consumption and suppression of some imperfections of new and older engines. (For example: the impact of regulation on the engine operation). The patented technology application of auxiliary electrode coating to the tip of the insulator ensures the unique properties of the spark plugs. The alignment of the individual indicated medium pressures and the displacement of their diameters to the upper limit in the final consequence increases engine power. The reduced voltage requirement from the ignition system expands their use.

Spark plugs with silver centre electrode of small diameter, especially suitable for engines powered by LPG and CNG as well as racing engines.

Replacement interval: see table below.

The use of gaseous fuel saves the users considerable financial resources and is more environmental friendly. BRISK Tábor places great emphasis on ecology and therefore developed the SILVER special spark plug range, which has been used for many years by customers from all over the world. The spark plug design eliminates problems caused by the different characteristics of LPG and CNG fuel from the original installation when running on petrol. The high thermal conductivity of silver offsets the higher heat stress without changing the thermal value of the spark plug and thoroughly covers the requirements of the engine even when running on petrol. The shape of the electrode and smaller electrode gap reduces the demand on voltage supplied by the ignition system. The open spark gap does not hinder propagation of the flame front and ensures perfect burning of the mixture, which is advantageous even when using the SILVER range spark plugs for racing engines.

Spark plugs for racing purposes with special design spark gap.

Replacement interval: max. 50 engine hours

The advantage of this special spark plug range is spark-over from the shell around the full circumference (360°). The design makes them suitable for high performance engines. A great advantage is perfect ignition of the air-fuel mixture in the combustion chamber.

Spark plugs with long flash-over with a possibility of spark-over around the full circumference (360°).

Replacement interval: see table below.

The advantage is perfect ignition of the air-fuel mixture in the combustion chamber. The discharge is unrestricted around the entire perimeter of the insulator tip. The Premium LGS range spark plugs require powerful ignition systems, perfect blending of mixture and utilisation of the engines in the high-rpm zone.

Spark plugs with two auxiliary electrodes on the surface of the insulator tip. Three sparks in series at one impulse of the ignition system with a possibility of spark-over around the full circumference (360°).

Replacement interval: see table below.

Auxiliary 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. The special spark gap protrudes deep into combustion chamber, thanks to which the mixture is perfectly ignited in the combustion chamber. 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 Premium ZC spark plug has a centre electrode with copper core and the Premium ZS has a silver centre electrode.

Spark plugs with silver centre electrode, special design, adapted to high thermal load, vibrations and pressures.

The open spark gap does not hinder propagation of the flame and ensures perfect ignition of the mixture. Unlike standard spark plugs with the same thermal properties, the silver centre electrode makes it possible (thanks to its higher thermal conductivity) to use a larger surface area of the insulator tip and hence ensure longer protection against contamination with conductive deposits.

Replacement interval: see table below.
