Common Uses

• Rough idle caused by worn or fouled spark plugs
• Hard starting from weakened ignition output
• Misfire conditions tied to aged secondary ignition components
• Reduced throttle response from inconsistent spark delivery
• Maintenance replacement for OE-style nickel-copper plug applications

Installation Notes

Verify the required gap and thread reach before installation. This plug is listed with a 1.1 mm pre-gap, while several fitments note a 0.044 in gap requirement; confirm the engine specification for your exact vehicle before use. Check the seat type, thread diameter, and heat range against the original plug specification, especially on Jeep Liberty, Dodge Dakota, Honda Civic, and Mazda Protege applications.

Use proper spark plug removal and installation procedures to avoid thread damage in the cylinder head. Inspect ignition wires or coil-on-plug components at the same time so the new plug is not installed into a worn secondary ignition system.

Quality Assurance

Bosch manufactures this spark plug to meet or exceed original equipment specifications for nickel-copper core applications. The Bosch 79015 part number is built for conventional ignition service where OE-style materials, resistor performance, and correct fitment are required.
