Removal and Replacement of Spark Plugs

Model: BMW X5 E53 - Years 1999-2006
Part: Spark plugs

First, perform this repair with the engine cold to safely handle the parts involved.
Open the hood, remove the 4 screws securing the engine cover, and take it off; then detach and remove the side protective covers.
Release the connector attached to the boot from the lock and disconnect it; pull out the boot and unscrew the spark plug.
Carefully install the new spark plug, ensuring not to exceed the torque specifications; before inserting the boot, clean the electrical contacts (both the connector and the spark plug terminal) with appropriate spray: then insert the boot and connect the corresponding connector, securing it in place.
Repeat the same process for the other spark plugs: you may need to remove some components that obstruct the removal of the boots.
