Detailed Product Description

The Bosch Nickel Spark Plug 79026 features a nickel center electrode core combined with copper to enhance conductivity and heat dissipation. The single ground electrode with a standard tip design ensures stable spark generation. Its ceramic insulator provides electrical insulation and thermal resistance, while the non-projected insulator type helps maintain consistent ignition timing. The flat seat design and precise thread diameter of 14 mm ensure proper fitment and sealing in Volkswagen Beetle engines. The 10,000 ohm resistor built into the plug reduces electromagnetic interference, protecting vehicle electronics.
