BRISK spark plug NR14S Silver series

The BRISK NR14S Silver spark plug is designed for motorcycles, including specific BMW models. Thanks to its small-diameter silver centre electrode, it offers high thermal conductivity, which is essential for reliable performance. Its design is optimised for engines running on LPG and CNG, but it is also suitable for standard petrol engines. You will also appreciate this spark plug in racing engines, where it ensures reliable ignition of the mixture even under heavy loads.

Silver electrode for high performance

The heart of this spark plug is a small-diameter silver centre electrode. Silver as a material excels in high thermal conductivity, which effectively dissipates heat from the most stressed parts and protects the spark plug from overheating. This heat dissipation capability is crucial especially in racing engines, which experience extreme thermal loads. At the same time, the small diameter of the electrode reduces the voltage required for the spark to jump, contributing to overall ignition reliability.

Optimised for LPG, CNG and racing engines

The design of the spark plug is tailored to the specific requirements of alternative fuel engines. LPG and CNG engines have a higher mixture ignition temperature, so the spark plug uses a smaller electrode gap to make it easier for the spark to jump. In addition, the open spark gap ensures better access of the fuel mixture to the initial flame. This results in faster and more efficient combustion of the mixture, which you will appreciate not only in gas-powered engines but also in high-performance racing engines.
