The ground and center electrodes are able to retain a precise gap, while also creating a greater spark. For example, the NGK G-Power Spark Plug, 4-Pack uses a G-power platinum alloy that enhances its performance. Look for a spark plug that is able to improve your gas mileage and provide a faster start. You don’t want to invest money in a spark plug that won’t deliver reliability and durability. Depending on the type of machine, you will most likely be able to replace the spark plugs on your own, without having to schedule an appointment with a mechanic.Īs you begin shopping for the best spark plug, you’ll want to first make sure the plug meets International Organization for Standardization (ISO) and Society of Automobile Engineers (SAE) standards. Spark plugs are responsible for creating the electricity needed to ignite the fuel mixture to start the combustion process and turn on the engine. This includes automobiles, lawnmowers, watercraft and aircraft. So, if you are looking to save up on some money and can make do with the RC12YC, that’s your go-to option.All machines that use gasoline engines are outfitted with spark plugs. Simply put, XC92YC is a much more expensive spark plug than RC12YC. The price factor may help you decide on one if you can use either of these plugs. You have to consider the requirement for your engine first. You must go through your needs and see whether you need a resistor-type plug or a non-resistor one.įinally, coming to the pricing, you get an apparent difference that can help you decide on the spark plug. 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. Type Of Plug Click On Image To View On Amazon.But if you have a powerful engine, you can go with the XC92YC. If you have a smaller engine, you pick the RC12YC. Is there are better spark plugs in terms of the gap? Well, there is no clear answer to that. This spark plug will easily work on a smaller engine and will have enough power for ignition without any trouble. You can see the difference between the gap is quite significant. On the other hand, the RC12YC spark plug has a gap of around 0.035inches. 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.

A Quick Comparison Table Specifications Champion XC92YC Champion RC12YC Top material Alloy steel Metal Gap 0.5inches 0.035-0.040inches Type of spark plug Standard plug Resistor-type spark plug Pricing Higher Lower Champion XC92YC Vs. 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. A common misconception is that Champion XC92YC and RC12YC are both the same spark plugs.
