Description

The Bosch EVO Spark Plugs 8505 are designed for reliable ignition in modern engines, including turbocharged gasoline direct injection (GDI) applications. These spark plugs feature an improved insulator design and high dielectric strength to withstand irregular combustion, also known as mega knocking.

Additional features include enhanced mechanical strength for durability during installation and optimal gas seal, improved corrosion protection with nickel-coated housing, and thermomechanical strength to resist irregular burns. The center electrode is made from a nickel-chromium-iron and copper core with an iridium tip, while the ground electrode features a copper core with a platinum and nickel-chromium-iron and copper tip. These spark plugs are sold individually.
