The easiest way to check what kind of spark plug your mower needs is to check at your local hardware store. If you have the make and model the sales associates should be able to help you find the right plugs for your machine.
Push mower spark plugs usually have pitch thread sizes of 1 millimeter to 1.5 millimeters. Aside from this, the thread`s diameter ranges from 10 millimeters to 12 millimeters. Their thread length or reach is from 9 millimeters to 12 millimeters.
Are all lawn mower spark plugs the same? No, all lawn mower spark plugs are not the same. Spark plugs are engine specific and there are different sizes and heat ranges (voltage requirements).

While you should buy spark plugs in matching sets for your vehicle, not all spark plugs are universal. Spark plugs come in different sizes with different gaps and are manufactured using a variety of metals. Finding the ones that you need can be difficult.
For your engine to remain at optimum performance, it is recommended to replace your spark plugs once a year or after 30 engine hours. Since your lawn mower needs regular, annual maintenance, it is easiest to include replacing spark plugs as part of your maintenance routine.
For the majority of plugs, you need a 5/8” or 16mm socket. Some Fords use 9/16″ plugs, some newer European and Asian vehicles use 14mm plugs, and there are a few applications that use 7/8″, 13/16″, ¾” or 18mm plugs. All spark plugs are 6 sided, except some BMW engines.
Spark plugs aren`t universal; you have to make sure that you buy one that fits your mower. You can consult your owners` manual to determine the types your lawn mower can use or take a look at the plug`s ceramic insulator, which usually has the number printed on it.
The different types of spark plugs can seem overwhelming at first, but the simple way to find out what kind of spark plug you need is by checking your owner`s manual. The manual will specify the right plugs for your vehicle.

Be sure to use the right spark plug! Although several different spark plugs may screw into the engine, using the incorrect one will result in performance problems and possible internal engine damage.
Incomplete combustion can also occur when the spark plugs can`t fully ignite the engine`s air/fuel mixture. This will probably cause your engine to start smoking.
Ideally, you want a metal that both conducts heat away fast and conducts current well. This means the spark plug would provide the best ignition and then conduct the residual tip heat out through the cylinder head quickly as well, for maximum performance and detonation resistance.
