AR14YS – SPARK PLUG SILVER AR14YS (CR7E / CR7EIX Equivalent)

THE SPARK PLUG

The BRISK AR14YS Silver Racing spark plug is a high-performance ignition solution designed for demanding race engines, tuned applications, and alternative fuel systems requiring strong and consistent combustion stability.

Featuring a 1.5mm silver wire centre electrode paired with a conventional open hook-type ground electrode, the AR14YS delivers exceptional ignition performance in high-octane and difficult-to-ignite fuel mixtures. It is especially effective with alternative fuels such as E85, methanol, ethanol, LPG, CNG, propane, LNG, race fuels, and nitro applications.

Silver is the most thermally and electrically conductive material used in spark plug construction. It rapidly dissipates heat from the firing tip, resulting in lower operating temperatures and a significantly stronger spark. This improves flame front speed, combustion efficiency, and overall engine responsiveness at high RPM.

The AR14YS also features a projected tip design, improving flame kernel positioning for more efficient combustion. It is compatible with a wide range of ignition systems, from basic coil and distributor setups through to modern high-energy electronic and direct ignition systems.
