As a proud owner of a Rzr 800, I can confidently say that the spark plug is an essential component of this vehicle. Without it, my Rzr would simply not run. But why exactly is the spark plug so necessary? Let me share with you my personal experience and knowledge.
Firstly, the spark plug is responsible for igniting the fuel-air mixture in the engine’s combustion chamber. This tiny but mighty component creates a spark that ignites the fuel, which in turn produces the energy needed to power the vehicle. Without a functioning spark plug, the engine would not be able to start or run.
Moreover, regular maintenance and replacement of the spark plug can greatly affect the performance and efficiency of your Rzr 800. Over time, dirt and debris can accumulate on the spark plug, causing it to become less effective in creating a strong spark. This can result in poor fuel economy, decreased power, and even engine misfires. Therefore, it is crucial to regularly check and replace your Rzr’s spark plug to ensure optimal performance.
In addition to its technical importance, the spark plug also plays a role in diagnosing potential issues with your Rzr’s engine. A fouled or damaged spark plug can indicate problems such as incorrect
My Buying Guide on Rzr 800 Spark Plug
As a proud owner of a Rzr 800, I understand the importance of maintaining its performance and efficiency. One crucial component that plays a significant role in this is the spark plug.

It is essential to choose the correct heat range for your Rzr 800 based on its usage and environment. A colder heat range is suitable for intense riding or high altitude areas, while a hotter heat range works best for casual riding or low altitude areas.
Consider Aftermarket Options
If you are looking for better performance from your Rzr 800, you may want to consider aftermarket options for your spark plugs. These options may come with features such as multiple electrodes or extended insulator tips that can improve ignition and combustion efficiency.
