Moreover, what is RC12YC in NGK?

The NGK I stock as an equivalent to the RC12YC is the BCP(R)5ES (6130).

In respect to this, is the RC12YC the same as the QC12YC spark plug? From what I can find the two plugs have the same heat range so are interchangeable without any difference in mechanical engine performance. BUT if you have a fuel injected engine you should use the QC plug. It's internal electrical construction is different to work properly with fuel injection systems.

Hereof, can I use RC14YC instead of RC12YC?

EITHER RC12YC or RC14YC will work. But for best results use NGK BKR5E or BKR6E. They last longer and are less prone to fouling.
