Wide range spark plugs with extended replacement interval.

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

Two or three ground electrodes, or special design spark gap and electrodes (DOX15LE-1), which makes it possible to extend the replacement interval up to 60,000 km. Centre electrode with copper core and higher thermal conductivity ensures perfect function in all engine operating conditions. Some types allow alternative discharge from the combustion deposits on the insulator tip.

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.

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

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

The most modern BRISK spark plug at present. The design and materials used fulfil all the current requirements of modern engines. Particularly the low requirement for voltage supplied by the ignition system, open spark gap into combustion chamber and suppression of the quenching effect.
