Does changing spark plugs on a Passat require removing the intake pipe?

[RileyFitz]

Changing spark plugs on a Passat does not require removing the intake pipe. The spark plugs are generally located inside the engine cylinders, and they become clearly visible after removing the high-voltage ignition coils. Spark plug replacement procedure: Open the hood, lift the plastic engine cover, remove the high-voltage ignition wires, and mark each cylinder's position to avoid confusion. Use a spark plug socket to remove the spark plugs one by one. When removing them, check for any external debris like leaves or dust and ensure thorough cleaning. Place the new spark plugs into the spark plug holes, hand-tighten them a few turns, then use the socket to tighten them properly. Reinstall the high-voltage ignition wires according to the firing order and secure the cover. Spark plug replacement interval: Under normal maintenance conditions, replacement is recommended every 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine type, so it's advisable to follow the owner's manual. Platinum spark plugs should be replaced at 40,000 km, standard nickel alloy spark plugs at 20,000 km, and iridium spark plugs between 60,000-80,000 km.
