Description
Overview:
The Champion Spark Plug RN12YC is a copper-core resistor spark plug for reliable ignition in small petrol engines found in construction and garden machinery. The copper core improves heat transfer and conductivity for a consistent spark under load, while the resistor design helps suppress electrical interference with ignition systems and electronics. It uses a standard M14 x 1.25 thread with 19 mm (3/4") reach and a gasket seat to ensure a secure, gas‐tight fit. A fixed terminal provides a stable connection to the plug lead. Built with a robust shell and wear-resistant electrodes, the RN12YC suits routine maintenance on equipment such as mowers, generators, compactors and pumps, helping restore smooth starting, stable idling and efficient running. Supplied individually (each).
Key Features:
- Copper core centre electrode for strong spark and effective heat control
- Resistor (R) type to reduce radio frequency interference (RFI)
- M14 x 1.25 thread, 19 mm (3/4") reach for common small-engine fitments
- 14 mm thread diameter compatible with many garden and construction engines
- Gasket seat for a reliable, gas-tight seal
- Fixed terminal for a secure plug lead connection
- Durable construction for long service life in dusty and high-vibration environments
- Aids cold starting, smooth running and fuel efficiency when correctly gapped
- Suitable replacement for routine maintenance across mixed fleets
Typical Applications:
Ideal for lawn mowers, ride-on mowers, generators, plate compactors, concrete saws, cultivators, chippers, log splitters, pressure washers and water pumps using an M14 x 1.25, 19 mm reach gasket-seat plug.
Also known as:
RN12YC spark plug, copper core spark plug, resistor spark plug, M14 long‐reach (19 mm) gasket-seat spark plug, small engine spark plug, Champion RN12YC Copper Plus.
