Now, coming to the choice between the two, there is no better option. That’s why many racing plugs are standard plugs with no resistor because they need a quick and easy ignition to get more speed. This makes it very easy to start ignition. This means the plug can resist some of the energy when the engine is putting out spark energy, making it difficult to ignite.Īs for XC92YC, you get a pretty standard and powerful spark without resistance. The RC12YC spark plug is a resistor-type spark plug. Here, you are dealing with a standard and a resistor type. You may already know that there are several types of spark plugs. The key difference between these two spark plugs is their types.

As a result, you can’t use this spark plug for a smaller engine. Since the gap is large, the engine needs too much power to ignite the plug. In the XC92YC spark plug, you get a large gap of around 0.5inches. The spark plug gap is significant in determining the proper use of your spark plug. Because of that, there won’t be much difference in performance.īoth the spark plugs come with different spark plug gaps on them. Keep in mind that both spark plugs have the same core material. But if there are no special requirements, then you can go with the RC12YC as well. So, if you need a spark plug with alloy steel on top, Champion XC92YC is the way to go. This allows the spark plug to be used in more cases compared to the XC92YC. Otherwise, the plug isn’t just compatible with the engine.įor the RC12YC, the top material you have is just regular metal. Because of that, you get good sturdiness coming from it.Īlso, in some engines, you may need alloy steel. The XC92YC has alloy steel as the top material. This can lead you to decide which is the better option for your purpose. The crucial difference you can notice between the two options is the top material.

Stick until the end of this article to find out how each is different and where you should be using each of them. So, if you want the best solution for your engine and something perfect for your engine, then this will help you. Here, I will take you through the talk on Champion XC92YC vs. However, there are specific differences between the two options for your lawnmowers. There may be minor variations from the tabulated values for the less common plug types.A common misconception is that Champion XC92YC and RC12YC are both the same spark plugs. The tabulated values generally hold true for the more common plug types.
