Hello readers welcome to the new post. Here we will discuss What Size Socket for Spark Plug Needed? 2023 Complete Guide. If you are a car lover and enthusiast or have a regular vehicle owner, there will be chances that you will face a change in spark plugs at some point. Spark plugs are important in the combustion process of an inner combustion engine. With time, they wear out and have to be changed to maintain optimal engine performance. But what size socket for spark plug replacement is needed? In this post, we will cover the details of selecting the right socket size for changing spark plugs. So let’s get started with what size socket is a spark plug.
Introduction
Spark plugs are the main components of an internal combustion engine, and offer the spark needed for the ignition air-fuel mixture. To change them we need the accurate socket size to make sure smooth and effective process.
Why Spark Plug Socket Size Matters
The use of an accurate spark plug size is important for proper replacement. The socket which is very small will not fit accurately, while that is too larger can damage the plug. It is important to match the socket size accurately with a spark plug to minimize mishaps.

What is a Spark Plug Socket?
A spark plug socket is a special tool made to safely and effectively eliminate and install spark plugs in internal combustion engines. Unlike a regular socket wrench, a spark plug socket comes with a rubber insert or a magnet that securely holds the spark plug in place, avoiding damage during removal or installation.
What is a Spark Plug Socket For?
The main motive of a spark plug socket is to offer a snug and secure fit to the spark plug, helping mechanics to exert the necessary torque for removal or installation without causing any damage. It makes sure that the spark plug has proper alignment and avoids slippage that can cause by a conventional socket wrench.
Two Types of Spark Plug Sockets
There are 2 main types of spark plug sockets:
- Rubber Insert Spark Plug Socket: This type of socket comes with a rubber insert that conforms to the shape of the spark plug. It offers a cushioned grip and minimizes the chances of damaging the spark plug’s ceramic insulator.
- Magnetic Spark Plug Socket: Magnetic sockets come with a magnet embedded in the socket wall. The magnet holds the spark plug accurately in place, helping easy removal from tight spaces.
What Are The Common Sizes Of A Spark Plug Socket?
Spark plug sockets normally come in 2 common sizes:
- 5/8 Inch (16mm): This size is very common and fits a majority of spark plugs.
- 13/16 Inch (21mm): This large size is mostly used for larger spark plugs.

Ignition System in Cars
An ignition system in cars is a main parameter for starting the internal combustion engine. Its main work is to ignite the air-fuel mixture in the engine cylinder at an accurate time to start the combustion process, which produces the power needed to propel the vehicle.
The basic components of an ignition system are explained here
- Battery: The car’s battery offers the electrical energy required to power the ignition system. It provdies the initial voltage to start the process.
- Ignition Switch: The ignition switch is lies on the steering column or dashboard. When turned to the “ON” position, it starts the ignition circuit and allows current to flow from the battery to the rest of the system.
- Ignition Coil: The ignition coil is a high-voltage transformer that transforms the relatively low voltage from the battery into a high-voltage current, normally in the range of thousands of volts. This high-voltage output is important for producing a strong spark across the spark plug electrodes.
- Distributor (or Ignition Module): In older ignition systems, a distributor is employed to route the high-voltage current from the ignition coil to each spark plug in the accurate firing order. Newer vehicles mostly use an ignition module or direct ignition system, which reduces the need for a distributor.
- Spark Plugs: Spark plugs are important components that make the spark required to ignite the air-fuel mixture. They are located in the engine’s cylinders and have a gap across which the high-voltage current jumps to make the spark.
- Spark Plug Wires (Ignition Wires): In systems that use a distributor, spark plug wires attached the distributor cap to the single spark plugs, providing the high-voltage current to every cylinder in the accurate order. In distributor systems, individual coils often exist near each spark plug.
The ignition process comes with these steps
- The ignition switch is turned to the “ON” position, activating the ignition circuit.
- The battery sends a low-voltage current to the ignition coil.
- The ignition coil converts the low voltage into a high-voltage current.
- The distributor (or ignition module) sends the high-voltage current to the spark plugs in the accurate firing order.
- The spark plugs generate a spark across their electrodes, igniting the air-fuel mixture in the cylinders.
- The combustion process started, produces power that works the engine’s pistons, and ultimately propels the vehicle.

The Size and Applications of a 14mm Spark Plug Socket
A 14mm spark plug socket is a tool employed to remove and install spark plugs that comes with a 14mm hex size. It is a common size for spark plugs in newer European and Asian vehicles, and also for motorcycles.
Here are some of the uses of a 14mm spark plug socket:
- Removing and installing spark plugs in newer European and Asian vehicles, also motorcycles.
- Working on vehicles with difficult-to-access spark plugs, as a deep socket will have more clearance to work with.
- Repairing lawnmowers and other small engines that use 14mm spark plugs.
It is good to note that not all 14mm spark plug sockets are made equal. Some sockets are created with thin walls, which makes them easy to get into tight spaces. Others have a magnetic end, which helps to avoid the spark plug from falling out when you are trying to remove it.
When selecting a 14mm spark plug socket, it is good to consider these parameters
- The type of vehicle we are working on.
- The location of the spark plugs.
- The clearance is available.
- Your budget
What Size Socket For Honda Lawn Mower Spark Plug?
The spark plug socket size for a Honda lawn mower spark plug is 13/16 inches (21mm). it is the most common spark plug socket size for Honda lawnmowers, but it is always good to check the owner’s manual to be sure.
Here are some points for selecting the right spark plug socket for your Honda lawn mower:
- Ensure the socket is the accurate size for your spark plugs. If the socket is too small, it will not fit with the spark plug. If the socket is very large, it can damage the spark plug.
- Correct socket with a comfortable grip. There will be using a lot of force to loosen and tighten the spark plugs, so we need a socket that is easy to hold on to.
- If you are working on a lawn mower with difficult-to-access spark plugs, uses a deep socket. A deep socket will help us more clearance to work with.
- If you do not confirm what size spark plug socket you need, it is always good to err on the side of caution and get a larger socket. A larger socket will fit with most spark plugs, also if it is not the accurate right size
Do I Need A Special Socket Set To Remove Spark Plugs, Or Will Any Socket Set Work?
No, there is no need for a special socket set to remove spark plugs. Any socket set with the accurate size socket will work. Though, there are some things to note when selecting a socket set for spark plugs:
- The socket must be the accurate size for the spark plugs in the vehicle. You can find the spark plug size in your vehicle’s owner’s manual.
- The socket must be deep enough to fit with the spark plug and helps us to get a good grip on it.
- The socket must be created with durable material that will not damage the spark plug.
- The socket also has a comfortable grip so that we can apply even pressure when loosening and tightening the spark plugs.
If you are not sure what size socket you needed, it is always good to err on the side of caution and get a larger socket. A larger socket will fit with most spark plugs, though if it is not the accurate right size.
Here are some more safety tips for removing spark plugs:
- Ensure the engine is cool before starting to work on it.
- Wear safety glasses to protect our eyes from flying debris.
- Use a torque wrench to tighten the spark plugs to the proper features
