Product Details
The Champion Copper Plus line focuses on straightforward ignition service with a copper core center electrode that helps carry current efficiently while managing heat transfer. On this part number 880, the nickel center electrode tip and nickel copper alloy ground electrode support consistent spark delivery and normal wear behavior in service. The removable nut terminal and resistor construction make it suitable for ignition systems that call for this configuration. For Porsche 911 maintenance, the 880 spark plug matches listed applications across 1974, 1976-1977, and 1981-1989 model years.
This part cross-references DENSO Auto Parts 5044 and Autolite 403 for the same application.
What It Helps Address
- Hard starting caused by worn or inconsistent spark plugs
- Misfire from weak ignition output at the plug
- Rough idle related to degraded secondary ignition performance
- Loss of throttle response from aged spark plug electrodes
- Electrical interference concerns in resistor-equipped ignition systems
Installation Notes and Tips
Verify the plug type RN3C, 14 mm thread diameter, 0.75 in reach, and flat seat before installation. Check the gap against the vehicle specification; this plug is pre-gapped at 0.025 in / 0.64 mm, while listed Porsche 911 applications note 0.024 in for 1981-1989 and 0.028 in for 1974. Confirm the ignition system calls for a resistor spark plug and inspect the threads and seat condition before torquing to specification.
