Spark plug (CZ) - BRISK N17C

Single-electrode wide-range spark plug BRISK  is designed for reliable operation across a wide range of operating conditions. It is equipped with a center electrode made of a special alloy, which is filled with a copper core featuring high thermal conductivity. This design ensures efficient heat dissipation from the combustion chamber, stable ignition performance, and reduces the risk of overheating even during prolonged engine load.

Thanks to its construction, the spark plug offers long service life, reliable cold and hot starting, and smooth engine operation. It is suitable for two-stroke and four-stroke engines, for everyday use, maintenance, and restoration of older motorcycles and machines. The wide heat range allows use under various operating conditions without negatively affecting ignition performance.

The spark plug is designed with emphasis on precise dimensions and compatibility with common ignition systems. When installed correctly and tightened to the recommended torque, it ensures long-term and trouble-free engine operation.

NOTICE: It is essential to strictly observe the specified tightening torque when installing the spark plug into the engine. Due to the reduction of thread diameters (downsizing), the prescribed tightening torque is becoming lower. The use of a torque wrench is necessary, and only in exceptional cases may an alternative method be used according to the instructions shown on the packaging.
