What is the normal gap for spark plugs?
1 Answers
Spark plug normal gap is generally 0.6~1.3 mm. Spark plug replacement procedure: Open the hood, lift the engine's plastic cover, remove the high-voltage distributor 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 external debris like leaves or dust and ensure thorough cleaning. Place the new spark plug into the spark plug hole, hand-tighten it for several turns, then use the socket to tighten it further. Reinstall the removed high-voltage distributor wires according to the firing order, then snap the cover back into place. Spark plug replacement interval: Under normal maintenance conditions, replace every 40,000~60,000 km. However, this may vary depending on brand and engine type, so always refer to 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 at 60,000-80,000 km.
