AR10S – SPARK PLUG SILVER AR10S (CR9EK / CR9EIX Equivalent)

THE SPARK PLUG

The BRISK AR10S Silver Racing spark plug is engineered for high-performance and alternative fuel applications where strong, consistent ignition is critical.

Featuring a 1.5mm silver wire centre electrode and a conventional open hook-type ground electrode, the AR10S delivers outstanding performance when igniting high-octane and harder-to-burn fuel mixtures. It is particularly effective with alternative fuels such as E85, methanol, LPG, CNG, and race fuels.

Silver is the best thermal and electrical conductor used in spark plug electrodes. Its superior heat dissipation lowers overall spark plug temperature while producing a stronger, more consistent spark. The result is faster flame front propagation, improved combustion efficiency, and smoother high-RPM operation.

The Silver Racing range performs reliably with both OEM and aftermarket ignition systems, from conventional coil setups to modern electronic and direct ignition systems.
