Is rc12yx the same as rc12yc in spark plugs?
I found lots of replacements for the Champion rc12yc but none for the yx. Are they the same spark plug? Why wouldn't anyone carry a spark plug for a lawn mower that's two years old?
Are RN12YC and RC12YC interchangeable?
I have interchanged them and it seems to work. Everything is the same apart from the hex wrench. The hex on the RN12YC is 13/16" (20.6mm) and on the RC12YC it is 5/8" (16mm).

Is the RC12YC the same as the RC12YX spark plug?
Not really, but that is the only plug Sears sells as a substitute. The RC12YC plug looks like it was designed for a gap of 0.035-0.040", while the RC12YX plug was clearly designed for the recommended 0.020" gap. The RC12YC electrode is a fat cylinder like most spark plugs, while the electrode of the RC12YX is cut down to about half of the diameter. I'd guess the special RC12YX makes it easier to start the engine on a single pull.
Can you use spark plug RC12YC in place of RC12YX?
yes
Is the RC12YC the same as the QC12YC spark plug?
Both are resistive type plugs. The "R" indicates a resistor plug and the "Q" a EMS (electromagnetic suppression) resistor plug used to reduce noise in sensitive digital electronic circuits. In automotive uses Champion lists some Saab's requiring this "Q" plug. Lawn and garden small engines substituting to the RC12YC plug works just fine. In fact Sears will send you the RC12YC as a OEM part even though the engine was shipped with QC12YC plugs.
