Detailed Description

Bosch Nickel line spark plugs focus on dependable operation in engines that call for a conventional nickel-copper core design. The Bosch 79013 uses a copper core center electrode to help transfer heat efficiently, while the nickel electrode materials support consistent spark delivery under normal service demands. This makes it a practical choice for maintenance on Toyota Tacoma, Toyota Tundra, Toyota 4Runner, Toyota Echo, Scion xA, Scion xB, and select Nissan and Lexus applications listed in the fitment data.

The Bosch Nickel product line is positioned as a value-oriented OE-style spark plug family for drivers who want a standard replacement built to factory-style specifications.

Common Issues This Part Can Help Address

• Rough idle caused by worn or fouled spark plugs
• Hard starting from weak or inconsistent spark output
• Misfire symptoms related to aged secondary ignition components
• Reduced fuel economy from degraded ignition performance
• Loss of throttle response in high-mileage engines

Installation Notes and Tips

Verify the engine calls for a 14 mm thread, 19 mm reach, flat-seat spark plug with a 16 mm hex before installation. Check the gap against the engine specification even though the plug is pre-gapped at .9, and inspect ignition wires or coil boots for wear at the same time. Use the removable nut terminal only with the correct connector style for the vehicle.

For fitment-specific service, confirm the application against the vehicle’s engine code and service information before installing Bosch 79013 in Toyota, Scion, Nissan, or Lexus models.

Quality Assurance

Bosch manufactures this spark plug to meet or exceed original equipment specifications for nickel-copper core spark plug applications. The Bosch 79013 is built with a ceramic insulator, resistor design, and conventional electrode materials to support consistent service in the listed vehicles.
