Why I Always Make Sure to Have Spark Plugs for My Stihl Trimmers

As a proud owner of a Stihl trimmer, I have learned the hard way that having spare spark plugs on hand is absolutely essential. In fact, I make it a point to always have at least one spare spark plug in my toolbox whenever I head out to do some yard work.

First and foremost, spark plugs are crucial for ensuring that your Stihl trimmer starts up and runs smoothly. They provide the necessary spark to ignite the fuel in the engine, allowing it to function properly. Without a functioning spark plug, your trimmer will simply not start, leaving you frustrated and unable to complete your yard work.

Moreover, even if your trimmer does start with a faulty spark plug, it will not run efficiently. This can lead to a decrease in performance and potentially damage the engine over time. By regularly replacing your spark plugs, you can ensure that your Stihl trimmer operates at its best and lasts for years to come.

Another reason why having spare spark plugs is important is because they can wear out over time. As with any engine part, regular use can cause wear and tear on the spark plug, causing it to lose

My Buying Guide on ‘Spark Plugs For Stihl Trimmers’

As a long-time owner of a Stihl trimmer, I have learned the importance of choosing the right spark plug for optimal performance. After going through numerous options and learning from my own experiences, I have put together this buying guide to help others make an informed decision when purchasing spark plugs for their Stihl trimmers.

Understanding Spark Plugs

Before diving into the specifics of spark plugs for Stihl trimmers, it is important to understand what a spark plug does and how it affects the performance of your equipment. A spark plug is responsible for igniting the air-fuel mixture in the engine, which ultimately powers the trimmer. A faulty or incorrect spark plug can lead to decreased fuel efficiency, misfires, and even damage to the engine.

Know Your Trimmer Model

The first step in purchasing a spark plug for your Stihl trimmer is to know your exact model. Each model may require a different type of spark plug, so it is crucial to have this information before making a purchase. You can find your model number on the label located on the engine housing or in the user manual.

Consider OEM vs. Aftermarket Spark Plugs

When looking for a replacement spark plug, you will come across two options – Original Equipment Manufacturer (OEM) and aftermarket spark plugs. OEM plugs are made by Stihl and are specifically designed for their trimmers. While they may be slightly more expensive, they are guaranteed to fit and perform well in your trimmer.

On the other hand, aftermarket spark plugs may be more affordable but may not always provide the same level of quality and compatibility as OEM plugs. It is important to research and read reviews before purchasing an aftermarket option.

Check Heat Range

Spark plugs come in different heat ranges that determine how much heat they can dissipate from the combustion chamber. For Stihl trimmers, it is recommended to stick with medium heat range (hotter than standard) as these engines tend to run hot.

Look at Electrode Material

The electrode material also plays a role in the overall performance of a spark plug. Most Stihl trimmers come with copper core electrodes which provide good conductivity and durability. However, you can also choose platinum or iridium electrodes if you want longer-lasting performance.

Check Gap Size

The gap size between the center electrode and side electrode is another important factor to consider when buying a spark plug. The gap size varies depending on your specific trimmer model, so be sure to check your user manual for this information.

My Top Recommended Spark Plugs for Stihl Trimmers

– NGK BPMR7A: This OEM option is ideal for most Stihl models and has excellent heat dissipation capabilities.
