Brisk Premium LGS spark plugs utilize a unique semi-surface discharge electrode design. This enables the plug to fire a much larger spark plug gap—because the spark glides along the surface of the insulator, requiring much less energy than firing a traditional-style air gap. Longer spark discharge makes more contact with the air/fuel mixture, igniting more molecules over a larger area. Order the LGS model and options preferred for your application. Additional product details: * High-potential semi-surface discharge equals more power * Discharge at point of richest mixture in 360 degrees perimeter * Patented firing tip design; no indexing or gapping required * Retracted integrated ground electrodes * Silver center electrode—the best thermal and electrical conductor

Brisk Multi-Spark spark plugs are designed to deliver three simultaneous sparks without any modifications to your ignition system. This unique patented design is beneficial for high performance and racing applications, and everyone who is seeking a more full and complete combustion cycle—as there is no shrouding of the sparks. By having the multiple sparks unshrouded, the plugs have direct access to the air/fuel mixture, which produces a more spontaneous and rapid flame propagation. This improves engine efficiency, as there are less imperfectly ignited cycles (reduction in emissions from unburnt air/fuels)—which is beneficial for racing and performance, as well as a producing an economically friendly product. Order the model and options preferred for your vehicle. Additional product details: * Multi-spark plugs increase engine power * More horsepower, torque, faster acceleration and response * Maximum spark exposure; better use of available energy * Silver center electrode—the best conductor of any metal Multi-Spark plugs are ideal for these applications: * Race engines with precise air/fuel management * Mild supercharged, turbocharged, or nitrous engines * All late model vehicles; better gas mileage

Denso Iridium TT spark plugs, with their unique Twin-Tip technology, have two "tips": a 0.4mm iridium center electrode, and a 0.7mm platinum ground electrode. First used with OE spark plugs for luxury and performance cars, they are the smallest mass-produced center electrodes available. They require lower voltage and feature high-ignitability, so there is less interference with spark growth (quenching) and the twin tips deliver omnidirectional ignition, unlike the flat "sandwich" ignition of other spark plugs. Denso selected iridium and engineered it with rhodium to build the most durable alloy for spark plugs. Their patented formula has the highest concentration of iridium of any spark plug and even under the most severe engine temperatures resists oxidation and voltage wear for extended periods. The superior ignition of Denso Iridium TT spark plugs means more efficiency, fewer misfires, and significantly improved combustion, optimizing power and fuel economy like never before. Order the model designed for your vehicle application. Additional features of Denso Iridium TT spark plugs include: * Revolutionary 0.4mm center electrode means significantly improved combustion and reduced misfires * Invented by Denso, Iridium TT Twin-Tip technology creates a larger flame front for more complete combustion * Precision 360 degree laser-welding technology ensures structural support for the iridium center electrode, even in the harshest combustion environments * Tested to last well beyond 100,000 miles, with minimal loss of performance, for greater lifetime savings than any plugs available today
