Description

The Bosch 8502 is an EVO spark plug engineered for reliable ignition and long service life, even under extreme engine conditions. Its improved insulator design and high dielectric strength (greater than 45 kV) allow it to withstand irregular combustion, such as mega knocking, common in modern engines.

This spark plug features a fine wire iridium center electrode and a platinum-tipped ground electrode, both with copper cores. It has a J-gap ground configuration, a non-removable nut electrical terminal type, and a projected insulator type with a manufacturer heat range of 6. The hex size is 14mm, and it is indexed for precise installation.
