RN12YC and RC12YC are not interchangeable. The "R" in RN12YC signifies a resistor plug, which helps reduce electromagnetic interference. The "C" in RC12YC denotes a copper core plug, which provides better heat dissipation. Using the incorrect type of spark plug can lead to poor engine performance and potential damage.
I was wondering the same thing this afternoon
The Champion RC12YC and RC12YX spark plugs are not interchangeable because they have different heat ranges and design features. The RC12YC is typically used in applications that require a cooler operating temperature, while the RC12YX is designed for higher performance. Always consult your engine's specifications or a professional to ensure you're using the correct spark plug for your specific application.
The spark plug that commonly replaces the RC12YC is the NGK BPR6ES. Both plugs have similar specifications and are interchangeable in many applications. It's important to verify compatibility with your specific engine to ensure optimal performance. Always refer to the manufacturer's recommendations when replacing spark plugs.
The Champion RC12YC and the Champion CH71ECO are not directly interchangeable, as they may have different specifications, such as heat range and design features. It's important to check the manufacturer's recommendations for your specific engine to ensure compatibility. Using the wrong spark plug can lead to performance issues or engine damage. Always refer to your engine's manual or consult with a professional before making a substitution.

A champion RC12YC spark plug is 14mm thread diameter. The torque for this size is 18-22 foot-pounds (25 to 30Neuton·meters)
Harley-Davidson uses .040" gap in their engines using this plug.
RN11YC can also use RN12YC
Yes, the RC12YC spark plug is a suitable replacement for the QC12YC spark plug. Both plugs have similar specifications, but the RC12YC is designed for a broader range of applications and may offer enhanced performance in some engines. Always consult your engine's manual or a professional to ensure compatibility and optimal performance.
