Sparkplug difference beetween a RC 12yc champion sparkplug vs qc12yc?

Answer 1

As we face the decision between Champion spark plugs that include the RC12YC and QC12YC, the main distinction in their features is the design of the resistor and manufacturing tolerances, even though they can be used in similar applications.

RC12YC: The RC12YC is the regular type of spark plug used in most small engines like lawn mower, Generators and other power tools. It has a center electrode of copper core that transfers good heat and is long-lasting.

QC12YC: QC12YC is like a projected tip, whereby the Q in the brand of QC12YC would mean projection tip, which allows the spark to be slightly recessed into the combustion chamber. This may offer high combustion efficiency and good engine performance, particularly, on special Briggs &

Stratton and Kohler.

Answer 2

The RC12YC and QC12YC are both spark plugs manufactured by Champion, but they differ mainly in their construction and intended applications. The RC12YC features a standard copper core and is designed for general use in various engines, providing good performance and longevity. In contrast, the QC12YC has a quad electrode design, which enhances ignition efficiency and improves performance in high-demand applications. This design can lead to a longer service life and better fuel efficiency under certain conditions.
