Q:
How to replace spark plugs in the BMW X3? Posted by Customer
A:
Both the M54 engine and the N52 engine utilize a coil-over-sparkplug configuration, with one ignition coil positioned above each spark plug. The recommended interval for replacing the spark plugs on these engines is 100,000 miles. It is important to note that the spark plug electrode gap is not adjustable. To replace the spark plugs, start by removing the engine cover and then unlock the ignition coil connector before pulling it off the coil. Slide the rod-shaped ignition coil straight out of the spark plug hole. It is crucial to maintain cleanliness during this process to prevent any fuel or oil residue from causing electrical resistance issues. Next, use a thin-walled spark plug socket to remove the spark plugs. If a thin-walled socket is not available for the N52 engine, carefully remove the slotted ignition coil sleeves from the cylinder head cover holes before removing the spark plugs. Inspect the spark plug electrodes, and if they appear light grey, it indicates normal combustion. When installing the new spark plugs, lightly lubricate the threads with a copper-based anti-seize compound. Thread the plugs into the cylinder head by hand to avoid cross threading. If the slotted ignition coil sleeves were removed, reinsert or replace them as necessary. Finally, carefully insert the ignition coils into the spark plug wells and reattach the electrical connectors.
