Spark plugs EXTRA

Wide range spark plugs with prolonged change interval

The centre electrode is from nickel alloy filled with cooper core. Two or three ground electrodes of BRISK Extra spark plugs enable the spark-gap construction which is opened into combustion chamber. This improves mixture ignition in the initial phase of ignition and inhibits flame extinction caused by heat transfer from electrodes.
The use of more electrodes extends change interval up to 60.000 km. Length stability of electrode gap and stability of thermal properties for long operating time predestine these spark plugs for use on wide variety of both, most up to date engines and engines of older construction.

These spark plugs are manufactured in two-electrode design with possibility of spark-over from burning deposits on insulator tip and in three-electrode design, too.
Correct choice of spark plug you find in catalogue BRISK.

Spark plugs PREMIUM

The unique patent-registered spark plugs




- completely new spark gap shape

- higher power

- better acceleration

- superior fuel energy utilization

.
LGSGS

Replacement CHANGE interval:
max. 30.000 km

Example of marking: DO15LGS, LOR14LGS, AR08GS...

PREMIUM ZC / ZS


Two auxiliary electrodes deposited on insulator tip with special patented technology enable simultaneous flashover of two surface sparks and one air spark by single impulse of ignition system. Each spark has chance to jump around full circumference of auxiliary electrode (360°). The spark gap protrudes deep into combustion chamber and improves initial flame front propagation. A number of sparks and sufficient distance between them decrease probability of incomplete ignition of mixture in combustion chamber and increase flame propagation rate and engine power.

ZC / ZS

Replacement CHANGE interval:
max. 20.000 km

Example of marking: DR14ZC, LR15ZC, L10ZS...

PREMIUM LGS / GS


Spark gap enabling surface flashover (extreme long) with the possibility of spark-over around full circumference 360°. Ignition spark will jump always at point of highest fuel concentration. Substantially higher flame propagation rate in the initial phase of flame propagation in the combustion chamber enables superior fuel energy utilization. The combustion velocity in conjunction with knock sensor assures engine-power increase. The spark gap of spark plugs BRISK PREMIUM "LGS" is protruded deep into combustion chamber.

Spark plugs A-line yttrium
