Bosch 79168 Spark Plug

Overview

Bosch 79168 is a conventional nickel-copper spark plug built for older ignition systems that call for a standard replacement plug. It uses a nickel center electrode with a copper core and a standard ground electrode layout to match OE-style service needs.

Compatible with Volkswagen and Volvo applications across a wide range of classic models, including Volkswagen Jetta, Volkswagen Rabbit, and Volvo 242. Bosch Nickel line spark plugs focus on conventional construction and OE-spec alignment for straightforward maintenance.

Key Features

• Nickel-copper core construction for conventional ignition service
• Standard ground electrode design with a flat seat
• Non-projected ceramic insulator
• Pre-gapped to 0.7 mm
• 14 mm thread diameter with 19 mm reach
• Resistor-free design for applications that specify a non-resistor plug

Detailed Description

Bosch 79168 spark plug is engineered to meet or exceed original equipment specifications for nickel-copper core spark plugs. The heavy-duty yttrium-enhanced nickel center electrode with copper core is intended to provide durable service in engines that use a conventional 4-cycle plug design. The Bosch 79168 is a practical choice for older Volkswagen Jetta, Volkswagen Rabbit, and Volvo 242 applications where the catalog calls for a nickel replacement plug with a 0.028 in gap note in fitment data.

This Bosch Nickel spark plug line is aimed at drivers and technicians maintaining legacy vehicles that need a direct-style replacement rather than a specialty performance plug. The combination of nickel electrodes, ceramic insulation, and standard seat geometry supports routine tune-up service on compatible Audi, Volkswagen, and Volvo models.

Installation Notes

Verify the specified gap and thread dimensions before installation. This plug uses a flat seat, 14 mm thread diameter, 19 mm reach, and 20.8 mm hex size, so matching the engine specification is important for proper service. Confirm the application notes for California emissions exclusions and original electrode material references where listed in fitment data.
