Is the RC12YC the same as the RC12YX spark plug?
No, the RC12YC and RC12YX spark plugs are not exactly the same, although they are similar.
Here are the key differences:
- RC12YC: This spark plug is commonly used in a variety of applications, including small engines, lawn mowers, and some automotive applications. It has a copper core and is designed for general use.
- RC12YX: This is also a spark plug with similar applications but often has a slightly different design, such as a different electrode material or tip configuration. The “X” designation can indicate differences in heat range or other features specific to certain applications.
Both spark plugs are from the same manufacturer (NGK) and have similar basic specifications, but if you’re replacing a spark plug, it’s always best to confirm the exact part number that your engine manufacturer recommends to ensure optimal performance.
