Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety.
Allow the engine to cool down before working on the ignition system.

2. Remove Engine Cover

Use a socket set to remove any fasteners securing the engine cover.
Carefully lift off the engine cover and set it aside.

3. Remove Old Spark Plugs

Locate the spark plug wires or ignition coils. If equipped with ignition coils, remove the electrical connectors.
Use a socket wrench with a spark plug socket to loosen and remove each spark plug. Turn counterclockwise until loose and remove them carefully.

4. Inspect and Install New Spark Plugs

Inspect new spark plugs for any damage or defects before installation.
Check the gap on new spark plugs using a feeler gauge and adjust if necessary to meet specifications (typically around 0.028-0.032 inches for most BMW engines).
Apply a small amount of anti-seize compound to the threads of the new spark plugs if recommended.
Install new spark plugs by hand to avoid cross-threading, then tighten to manufacturer specifications (usually around 15-22 lb-ft).

5. Reassemble Components

Reinstall ignition coils or spark plug wires, ensuring they are securely connected.
Reinstall the engine cover and secure it with fasteners.
Reconnect the battery.
