Spark Plug Socket Size And Wrench Models

A spark plug socket wrench is one of the workshop tools that serve to remove and install spark plugs on gasoline-fueled cars. The spark plug wrench is a special service tool because its use is only devoted to opening the spark plug according to the size of the existing spark plug.

Even so, in practice, a spark plug socket wrench is provided in cars when we buy a new car—generally placed together with other toolsets. With the spark plug socket wrench in the car tool set, when there is an engine problem, we can use the spark plug wrench to open the spark plug for inspection.

We can measure this spark plug socket size from the spark plug on the part made of metal with a hexagonal shape, which is generally located in the middle of the spark plug body. This size will also affect the size of the spark plug socket wrench that we will use.
