Spark plugs are engine parts that can be found in both cars and motorcycles. Spark plugs do something significant for vehicles, turning the voltage from the coil line into sparks.
In the engine room, the spark will soon burn the mixture of fuel and air.
When something goes wrong with a car or motorcycle, like if it breaks down, the condition of the spark plugs is the first thing to check, but to open the spark plug, you need a special key called a “spark plug key.”
There are different types of workshop wrench. The spark plug wrench is part of a set of special service tools, so it can only be used to take out or put in spark plugs. There are also different types and sizes of spark plug locks, depending on the vehicle type.
Spark plug keys for two-wheeled vehicles like motorcycles are usually 16 mm, 17 mm, 19 mm, or 21 mm long. The size of the key depends on what the spark plugs in the motor look like.
This key can be used for a motorcycle or motorcycle like a 16 mm spark plug wrench. As for the 21 mm spark plug wrench, it is often used on 2-stroke motorcycle engines.
Use a spark plug wrench between 16 mm and 20.8 mm to work on a car’s spark plugs.
For beginners, you can use a measuring tool to find out what size spark plug wrench you need by measuring the center of the metal body of the spark plug.
Then, what are the most common spark plug keys for cars and motorcycles? Let’s look at the explanation below to answer this question:
1. Spark Plug Wrench Pipe Model
The pipe spark plug wrench is a standard spark plug wrench that comes with most vehicles when bought. This key for the spark plug is a standard key that comes with the whole car.
Still, people who own cars can buy this spark plug wrench elsewhere for a price that isn’t too high. The end of a pipe spark plug wrench or uniortools is shaped like a hexagon.
Depending on the size of the spark plugs, this hexagon shape comes in different sizes. Spark plugs can also be taken out or put in with this part.
At the other end, there is a hole that the spark plug wrench goes through.
The pipe spark plug wrench comes with a spark plug wrench that is small and easy to store and carry because of its shape. The bad thing about this key is that it wears out quickly.
2. Shock Ratchet Spark Plug Wrench
The shock ratchet spark plug wrench is a spark plug wrench that usually comes as a set in a box.
The box has different sizes of spark plug wrenches, from 16 mm to 20.8 mm, as well as a flexible ratchet ring fitting and a handle or lever.
When taking out or putting in spark plugs, this shock ratchet spark plug wrench is helpful because it can be bent to change the angle.
Not only that, but this spark plug wrench has a ratchet that lets it take out and put in spark plugs faster than a pipe wrench.
3. Model T Spark Plug Wrench
As its name suggests, the T model spark plug wrench has a handle that looks like the letter “T.” When taking out or putting in spark plugs, this T-shaped handle is easy to hold on to.
Not only that, but this spark plug wrench is quite long and works great for grabbing spark plugs that stick out.
In addition to its length, the T spark plug wrench has a spring that makes it more flexible. So, the T model spark plug wrench makes it easy to reach the plug from a certain angle.
Those are some common locks for spark plugs on cars and motorcycles. Before getting the spark plug lock, it’s a good idea to find out the size of the car’s spark plug, so it can work properly.
In addition to the spark plug wrench, you should also know about other tools used in a workshop. This will help you figure out which tool to use when your car or motorbike breaks down.
