BRISK spark plug LR14YC Super series

Standard spark plug for Yamaha motorcycles, BRISK LR14YC Super, features a centre electrode with a copper core. This ensures increased thermal conductivity and helps protect against thermal overload. Thanks to the large surface area of the insulator tip, the spark plug offers reliable operation even under low loads. It is designed for use in a wide range of Yamaha motorcycle models, providing a reliable ignition mix.

Copper core and optimised insulator

The centre electrode with a copper core is a key feature of this spark plug. The copper material dissipates heat from the central part, increasing its thermal conductivity and allowing the spark plug to better withstand thermal overload. The design is complemented by a large insulator tip surface area, which ensures the self-cleaning temperature is reached quickly. The spark plug offers reliable operation even under low engine loads.
