What is a Spark Plug Socket?
A spark plug socket is a type of socket wrench that is specifically designed to fit and grip the hexagonal base of a spark plug. These sockets typically have a deep well design, allowing them to fully enclose the spark plug and provide the necessary leverage to remove or install it. The socket's depth ensures that the spark plug can be accessed and turned without damaging the delicate ceramic insulator or the threads in the engine's cylinder head.
Key Features of a Spark Plug Socket
- Deep Well Design: The socket has a deep well that allows it to fully enclose the spark plug, providing better grip and leverage.
- Hexagonal Shape: The socket's interior matches the hexagonal shape of the spark plug's base, ensuring a secure fit and preventing slippage.
- Spark Plug-Specific Size: Spark plug sockets come in various sizes to fit different spark plug diameters, typically ranging from 16mm to 24mm.
- Magnetic Tip: Some spark plug sockets have a magnetic tip, which helps hold the spark plug in place during removal and installation.
Using the correct spark plug socket is essential to avoid damaging the spark plug or the engine's cylinder head during service. Attempting to remove or install a spark plug with the wrong tool can lead to stripped threads, damaged spark plug insulators, or other costly repairs.
Choosing the Right Spark Plug Socket

Spark plug sizes are typically indicated by their diameter, such as 16mm, 18mm, or 22mm.
