Overview

The Brisk Racing ER10S is a set of four Silver Racing spark plugs designed for high-performance and race engines. These spark plugs utilize a smaller diameter silver core and a conventional open spark hook type earth electrode for outstanding performance, especially with high octane fuels and alternative fuel mixtures. Silver is highlighted as the best conductor of electricity and heat among common spark plug materials, promoting a more powerful spark and efficient combustion.
Show original supplier description
The Brisk Racing ER10S Silver Racing Spark Plugs are engineered for tuned and race engines, as well as vehicles running alternative fuels such as CNG, LPG, Propane, E85 blends, Alcohol, LNG, Race Fuels, and Nitro. These plugs feature a 1.5 mm silver center electrode, which is an excellent conductor of both heat and electricity, reportedly surpassing platinum and iridium in these properties. This superior conductivity results in a more powerful spark, leading to faster and better flame front propagation, smoother operation, and a higher RPM range. The design of the ER10S ensures proper firing even if fouling occurs, addressing a common failure point of standard plugs. They require lower voltage, which can reduce wear on coils, leads, and other ignition components. The plugs are compatible with most aftermarket and OEM ignition systems, from basic coil and distributor setups to modern electronic and direct ignition systems found in performance engines. With a service life of 30,000 km (18,000 miles) or 50 racing hours, these spark plugs are an excellent choice for a variety of applications, including naturally aspirated or forced induction setups, standard and high compression engines, high-mileage vehicles, and those with oil consumption issues. Specific parameters include a 14mm thread diameter, 26.5mm thread reach, 16mm (5/8") hexagon, gasket seat type, a resistor, and a heat range of 10. The ER10S is sold as a set of four.
