Brisk Premium Multi-spark plugs are an entirely new and patented type of high performance spark plug. The spark plug name describes exactly what the spark plug is all about: multiple sparks. The spark plug have no traditional so called "J-gap" ground electrode, instead, there are two auxilary ring shape electrodes bonded to the surface of the ceramic insulator. Since the ring shape electrodes are conductive, they split one very large gap into 3 smaller gaps for the sparks to occur. Since the Multi-spark plug 3 gaps are in series, the spark has to jump three times in order to get from the center electrode to the ground (the spark plug shell), as this is the path of the least resistance. This means that if your vehicle is equipped with a multi-spark ignition system such as Accel, Crane, Mallory or MSD, you will have 3 times as many sparks on the tip of the sprak plug than your ignition system generate. For example with MSD multi-spark ignition system you will get 9 sparks per every single primary ignition pulse until abut 3,000 RPM when the multi-spark ignition system switch into a single spark mode. But even than you will still get 3 sparks with the Brisk Premium Multi-spark plug, just as you will with a standard OE (original equipment) ignition system in ordinary cars, motorcycles and such.

Please do not mistake this unique high performance Brisk Multi-spark technology with an ordinary multi-ground electrode spark plugs, which produce only one spark per secondary ignition impulse, regardless of the spark plug multiple ground electrodes- the spark will occur only between one of the spark plug ground electrode as they are configured in parallel.

Owning to their unique design, Brisk Premium Multi-spark plugs do not have to be indexed as they do not have traditional "J-gap" ground electrode, and produce 3 sparks per each impulse of the ignition system. Each spark is not confined to a single place and can occur anywhere in the spark plug 360 degree perimeter. As each spark naturally occurs at the place of least resistance (lower pressure and optimal A/F mixture) sparks happen at the place most favorable for the ignition. More than one simultaneous point of ignition (3 sparks at same time in different locations) results in better, and more spontaneous ignition of the air-fuel mixture. Sparks are not shielded by the ground electrode; therefore it provides faster, unrestricted expansion of the flame front. The mixture burns more uniformly and more quickly. The result of better utilization of available combustion energy is more power, better acceleration, lower harmful exhaust emission and reduction in fuel consumption. Brisk Premium Multi-spark plugs are proven by multiple wins at DAYTONA SPEEDWAY and available in multiple heat ranges from stock applications to a full blown race cars.

Brisk Premium ZC is a spark plug that has no grounding electrode and provides three simultaneous sparks per one ignition impulse. Each spark occurs at the point of the biggest fuel concentration. Individual sparks are sufficiently distanced from one another, thereby ensuring perfect ignition of the air and fuel mixture. The mixture burns more uniformly and more quickly. This spark plug is suitable for clean burning engines with modern ignition systems.

Brisk Premium TXS spark plug generate 2 sparks per each primary ignition system, have one ring shaped auxilary electrode and 3 symetrical ground electrodes. TXS spark plus have been developed following several years of experience of the working and testing process of Brisk Premium spark plugs in various cars and climatic conditions. They extend the use of brisk Premium spark plugs for engines with less perfect air and fuel mixture, for engines intended for environment with low outside temperature or engines equipped with less powerful ignition systems such as points ignition. TXS spark plugs are available only in a couple of designs, an example can be Brisk Premium Multi-spark plug LR14TXS for applications such as Limbach small airplane engines, which are based on air cooled VW engines. LR14TXS is a popular spark plug for old air cooled 1.6 Liter VW and 2.0 Liter VW air cooled engines.

Spark Plug Silver Center Electrode - Silver is material with the most free electrons, for best spark plug performance. Silver is by far the best thermal and electrical conductor of all metals.
