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.

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.

Wide range spark plugs with centre electrode and iridium contact. Ground electrode from yttrium alloy with copper core.

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.
