Purchasing Lawn Mower Spark Plugs

Lawn mower spark plugs have a remarkably long life. In all likelihood, you will go through and replace one or two full lawn mower engines before you actually need to replace your spark plug. However, spark plugs do need replacing on occasion. Sometimes they are defective in some way, damaged from improper use or, miraculously, you’ve just managed to wear it out (which is only likely to happen if you mow lawns every day professionally).

Buying The Right Spark Plug

Spark plugs come in a variety of types depending on what they will be used for. Size and heat range are two factors that differentiate spark plugs. You need to make sure that they are set for the proper gap for your particular motor. They also need to be able to sit in the specific “seat” in your motor. Consult your owner’s manual on the specific type of spark plug needed for your particular model, or contact the manufacturer to be sure you are looking at the right lawn mower spark plugs at the store.

Where To Purchase Spark Plugs

Spark plugs are extremely common and cheap. Often you can find what you need for $3 or $4. Spark plugs are sold at just about any store that sells machines with combustion engines (combustion meaning gas law mower engines, versus an electric mower that has no spark plug).

You’re more likely to find what you need at a store supplying law mowers, especially if they sell your particular brand and model, but you may get lucky elsewhere, such as auto parts stores. The Internet is an easy way to find just about any part you would need for your mower, and as a last ditch effort, most manufacturer’s will sell replacement parts, even for their mowers that have been discontinued.
