Fortunately, manufacturers make it easy for you by providing specific codes and markings on the spark plug itself. These codes and markings indicate important information about the plug, such as its heat range and thread size.

The first step is to consult your lawn mower’s user manual to find out the recommended spark plug type for your specific model. Once you have this information, you can look for the corresponding code or marking on the spark plug. For example, you might see a code like “RJ19LM” or a marking like “CJ

When it comes to spark plugs, you might have noticed an alphanumeric code or marking on them. But what does it mean? Well, fear not! Decoding the alphanumeric code on the spark plug is actually quite simple. Let’s dig into it! The alphanumeric code on the spark plug is a combination of letters and numbers that provide important information about the spark plug’s characteristics.

Each letter and number in the code represents a specific feature of the spark plug. For example, the first letter in the code usually represents the heat range of the spark plug. The heat range indicates how well the spark plug dissipates heat.

This is important because if a spark plug has a too high or too low heat range for your engine, it can lead to problems like fouling or pre-ignition. The numbers in the code represent the thread size, reach, and gap size of the spark plug. The thread size refers to the diameter of the spark plug’s threads, while the reach refers to the length of the threaded portion.

The gap size, on the other hand, refers to the distance between the center and ground electrode. Understanding these codes and markings can be beneficial, especially when you need to replace your spark plugs. By knowing the heat range and other specifications of your spark plugs, you can ensure that you are using the right spark plugs for your engine.

So, the next time you take a look at your spark plugs and see those alphanumeric codes, remember that they hold valuable information about the spark plug’s characteristics. And now that you know how to decode them, you can make more informed choices when it comes to spark plug maintenance and replacement.
