    Designed for 2014-2019 Corvette LT1/LT4 applications, this Brisk Silver Racing spark plug stays within the stock heat range while delivering strong, consistent ignition under performance driving. The smaller-diameter silver core with an open-spark hook-type earth electrode helps light high-octane fuel mixtures reliably, even when common standard plugs can struggle due to fouling. Because silver is an excellent thermal and electrical conductor, it dissipates heat quickly for lower plug temperature and efficient spark energy, and its lower voltage requirement can help reduce wear on coils, leads, and other ignition components. Silver Racing plugs work well with most OEM and aftermarket ignition systems, from coil-and-distributor setups to modern electronic and direct ignition systems used on port- and direct-injection performance engines.
