Brisk Silver Racing spark plugs have a smaller diameter silver core and a conventional open ground electrode that provides excellent performance when igniting high octane fuel mixtures.

Silver metal is the best material for the core electrode of a spark plug because it can dissipate heat quickly, resulting in an overall lower spark plug temperature and a stronger spark.

The stronger the spark, the faster and better the flame front and flame speed, which leads to a smoother, higher speed range in engines.

The Brisk Silver Racing range works well with most aftermarket and OEM ignition systems, from simple coil and distributor to electronic ignition and high performance direct ignition systems used on modern port and direct injection engines.
