To replace the spark plugs on a Mercedes A-Class, start by removing the engine cover. Next, remove the air intake hose located above the spark plug tubes by loosening the clamps.

Once the air hose is off, proceed to remove the bolts securing the spark plug tubes. Disconnect the connectors from the tubes and remove the tubes.

After removing the tubes, take out the spark plugs using a socket wrench and extensions. Once all 4 spark plugs are extracted, blow out the spark plug tubes.

Position the new spark plugs in their seats and tighten them to the correct torque. Reinstall the tubes, reattach the bolts for the tubes, reconnect the connectors, reinstall the air intake hose by tightening the clamps, and put the engine cover back on.
