How to Replace Spark Plugs in Subaru XV?

[DiLevi]

Method for replacing spark plugs in Subaru XV: Open the hood, lift the plastic cover of the engine, remove the high-voltage distributor wires, and mark the position of each cylinder to avoid confusion. Use a spark plug socket to remove the spark plugs one by one. While removing them, check for any external debris such as leaves or dust, and ensure they are thoroughly cleaned. Place the new spark plugs into the spark plug holes, hand-tighten them for a few turns, and then use the socket to tighten them further. Reinstall the removed high-voltage distributor wires according to the firing order, and then snap the cover back into place. If the spark plugs are damaged, it can directly cause issues such as electrical leakage in the vehicle's ignition system, increased fuel consumption, reduced power, and most notably, difficulty in starting, which affects the normal operation of the vehicle. Severe erosion of the spark plugs—such as blistering, damage, or melting of the electrode—indicates that the spark plugs are ruined and should be replaced.
