FAQs
What are lawn mower spark plugs?
Lawn mower spark plugs are small, cylindrical devices that ignite the air-fuel mixture in the engine’s combustion chamber. They consist of a central electrode, a ground electrode, and a ceramic insulator. The spark plug receives electrical current from the ignition system, which creates a spark that jumps the gap between the electrodes, igniting the fuel. A spark plug is a crucial component for your lawn mower’s engine to operate properly.
Without a spark plug, the engine would not be able to start or run. The spark plug is also responsible for the smooth and efficient operation of the engine. A worn-out or damaged spark plug can lead to problems such as misfiring, poor acceleration, and decreased fuel efficiency.
How much does a lawn mower spark plug cost?
The cost of a lawn mower spark plug varies depending on the brand, type, and quality of the spark plug. However, you can expect to pay between $3 and $10 for a standard spark plug. Higher-quality spark plugs, such as those made by NGK or Champion, may cost more. It’s important to note that some specialized spark plugs for high-performance lawn mowers can cost upwards of $20.
The price also depends on where you buy the spark plug. You can usually find spark plugs at most hardware stores, auto parts stores, and online retailers. However, it’s always a good idea to compare prices before making a purchase.

Most lawn mower manufacturers recommend replacing the spark plug every 100 hours of use. However, you should check your owner’s manual for specific recommendations for your model. If you notice any signs of wear or damage on the spark plug, such as a cracked insulator, a worn electrode, or excessive carbon buildup, you should replace it sooner.
Replacing the spark plug regularly is crucial for the smooth operation of your lawn mower engine. A worn-out spark plug can lead to various problems, including misfiring, poor acceleration, and decreased fuel efficiency. It can also damage other engine components.
