Steps to Change Spark Plugs in a BMW E30
Once you have determined the spark plug socket size for your BMW E30, you can follow these steps to change the spark plugs:

- Open the hood and locate the spark plug wires. They are usually connected to the top of the engine and run to each spark plug.
- Remove the spark plug wire from the first spark plug by firmly pulling it straight off. Be careful not to pull on the wire itself, as it may damage the connection.
- Insert the spark plug socket into the socket wrench and attach it to the first spark plug.
- Turn the socket wrench counterclockwise to loosen and remove the old spark plug.
- Inspect the spark plug for any signs of damage or wear. If necessary, replace it with a new spark plug of the same size and specifications.
- Apply a small amount of anti-seize compound to the threads of the new spark plug to prevent it from seizing in the cylinder head.
- Insert the new spark plug into the socket and carefully thread it into the spark plug hole by hand. Make sure it is properly seated and then tighten it using the spark plug socket and wrench. Be careful not to overtighten.
- Repeat steps 3 to 8 for each remaining spark plug.
- Once all the spark plugs are replaced, reattach the spark plug wires to their respective plugs, ensuring they are securely connected.
- Close the hood and start your BMW E30 to ensure the spark plugs are working properly.
