AR12YS – SPARK PLUG SILVER AR12YS (CR8E / CR8EIX Equivalent)

THE SPARK PLUG

The BRISK AR12YS Silver Racing spark plug is a high-performance ignition solution designed for tuned, race, and alternative fuel engines requiring strong and stable combustion under demanding conditions.

Featuring a 1.5mm silver wire centre electrode paired with a conventional open hook-style ground electrode, the AR12YS delivers exceptional ignition performance in high-octane and hard-to-ignite fuel mixtures. It is especially effective in applications using alternative fuels such as E85, methanol, LPG, CNG, propane, LNG, and nitro-based race fuels.

Silver provides the highest thermal and electrical conductivity of any spark plug electrode material. This allows rapid heat dissipation from the firing tip, resulting in a lower operating temperature and a significantly stronger, more consistent spark. The improved flame front propagation leads to smoother high-RPM performance and enhanced combustion efficiency.

The AR12YS also features a projected tip design, improving flame kernel positioning within the combustion chamber for more efficient ignition. It is compatible with a wide range of ignition systems, including OEM coil setups, distributor systems, and modern high-output electronic and direct ignition systems.
