2014-2019 LT1 Brisk Premium LGS Spark Plug (One Step Colder)

Brisk Premium Racing Spark Plugs LGS feature a unique multi-ground electrode design and a silver core, delivering outstanding performance in igniting over-reach mixtures associated with tuned performance engines. As arcing occurs around 360 degrees and is not mixture-dependent, a larger gap is used at lower voltage levels, thereby increasing the ignition surface area.

Silver metal is the single best material for a spark plug's core electrode, as it dissipates heat quickly, resulting in lower overall spark plug temperature and a more powerful spark. The stronger the spark, the faster and better the flame front. Couple this to the multi-earth electrode design, and the need for a homogeneous mixture around a specific point, as is the case with a single-earth hook electrode. is not required.

Our LGS range works well with most aftermarket and OEM ignition systems, from simple coil-and-distributor setups to electronic ignition and powerful direct ignition systems found on modern port- and direct-injection performance engines.
