Brisk USA Performance Iridium Spark Plugs

The Brisk USA Performance Iridium spark plug line brings over 82 years of precision ignition engineering to performance street drivers, enthusiasts, and professional racing applications. As one of the world's largest spark plug manufacturers — producing over 50 million plugs annually — Brisk combines deep manufacturing expertise with patented combustion technology to deliver consistent, high-energy ignition across a wide range of engine types and fuel systems.

Proprietary Multi-Spark Discharge Technology

Brisk is the only spark plug manufacturer in the world to offer multiple discharges per single ignition system impulse. This exclusive, patented technology fires multiple times per cycle, promoting more complete combustion across the entire RPM range — delivering stronger throttle response, improved power output, and greater engine efficiency without requiring ignition system upgrades.

Advanced Iridium Electrode Construction

Iridium is 6x harder and 8x stronger than platinum, making it an exceptionally durable electrode material that significantly reduces spark plug gap erosion over time and extends service life well beyond standard copper or platinum alternatives. The copper-cored center electrode maximizes thermal conductivity, while the copper-cored ground electrode dissipates heat more efficiently — reducing the risk of pre-ignition and detonation during high-demand operation.

Key Features:

• Proprietary multi-spark discharge technology — exclusive to Brisk, firing multiple sparks per ignition impulse for more complete combustion
• Premium iridium center electrode — 6x harder and 8x stronger than platinum for exceptional gap erosion resistance and extended service life
• Copper-cored ground electrode reduces operating temperature by approximately 100°C (212°F), lowering the risk of pre-ignition and detonation
• Lower ignition voltage requirements — reduces strain on ignition coils, modules, and wires, extending their service life and supporting easier cold starts
• Yttrium-enriched ground strap alloy (select configurations) for reduced electrode wear and improved heat displacement
• Zn/Ni surface protection coating for superior corrosion resistance and prevention of plug seizure in the cylinder head
• High-alumina ceramic insulator with increased dielectric strength for reliable performance across all operating conditions
• Cylindrical insulator tip geometry promotes rapid self-cleaning temperature after cold starts and resists soft combustion deposit buildup
• Cut-back ground electrode design maximizes spark exposure and improves flame kernel development into the combustion chamber
• Engineered for stock, modified, forced induction, nitrous, and full race applications

The Brisk USA Performance Iridium line is available across a wide range of fitments and is compatible with gasoline, alcohol, E85, CNG, LPG, and propane-fueled engines — from daily drivers and track-day builds to dedicated high-output race applications. Each plug is manufactured to deliver consistent, high-energy ignition performance your engine can depend on, service after service.
