The Bosch Nickel product line is positioned for drivers who want a conventional spark plug that follows OE specifications for nickel-copper core applications. If you are servicing a Porsche 911, Boxster, Cayman, Panamera, or Cayenne and need a Bosch 79077 replacement, this plug matches the listed thread, reach, seat, and heat range details for the specified applications.

What It Helps Address

• Misfires caused by worn or eroded spark plug electrodes
• Hard starting from weak or inconsistent ignition output
• Rough idle related to degraded secondary ignition performance
• Reduced throttle response from aged spark plugs
• Ignition noise concerns in resistor-equipped systems

Installation Notes and Tips

Verify thread diameter, reach, seat type, and heat range against the vehicle’s service information before installation. Bosch 79077 is pre-gapped at 1.6 mm, but the gap should still be checked during service to confirm it matches the engine specification. Use proper spark plug removal and installation procedures to avoid damage to the ceramic insulator, threads, or cylinder head.
