Detailed Bosch EVO Spark Plug Features

The Bosch EVO spark plug line focuses on combining advanced electrode materials and precise design to optimize ignition in 4-cycle engines. The 8513 model features a fine wire center electrode made of iridium, which offers enhanced wear resistance and stable spark delivery. The ground electrode uses a platinum tip over a copper core, providing durability and consistent spark gap maintenance. The J-gap ground configuration and a single ground electrode ensure reliable ignition while maintaining efficient combustion. The ceramic insulator with a projected design improves voltage insulation and heat dissipation, supporting the manufacturer heat range rating of 6. Additionally, the integrated resistor helps minimize radio frequency interference, protecting vehicle electronics.
