MX5 Spark Plug Socket Size
What is a Spark Plug Socket?
A spark plug socket is a specialized tool used to remove and install spark plugs in an engine. It has a rubber insert or a magnetic feature that securely holds the spark plug in place, preventing it from falling into the engine bay.
Why is the Spark Plug Socket Size Important?
The size of the spark plug socket is crucial because it determines whether the socket will fit properly onto the spark plug. Using the wrong size socket can damage the spark plug or make it difficult to remove or install.

Steps to Remove and Install Spark Plugs in an MX5
- Ensure the engine is cool before starting.
- Locate the spark plug wires or ignition coils on top of the engine.
- Remove the spark plug wire or ignition coil by gently pulling it straight off the spark plug.
- Insert the spark plug socket onto the spark plug and turn it counterclockwise to loosen and remove the old spark plug.
- Inspect the old spark plug for signs of wear or damage. If necessary, replace it with a new one of the correct size and heat range.
- Apply a small amount of anti-seize compound to the threads of the new spark plug.
- Insert the new spark plug into the socket and carefully thread it into the spark plug hole by hand to avoid cross-threading.
- Tighten the spark plug using the spark plug socket and ratchet. Be careful not to overtighten.
- Reattach the spark plug wire or ignition coil to the spark plug.
- Repeat the process for each spark plug in the engine.
By following these steps and using the correct spark plug socket size, you can easily remove and install spark plugs in your MX5. Regular maintenance of spark plugs ensures optimal engine performance and fuel efficiency.
