How often should the spark plugs be replaced for the Sagitar 1.4T?

[WalkerFitz]

The replacement interval for the Sagitar 1.4T spark plugs depends on the type of spark plugs used. If platinum spark plugs are used, they should be replaced every 40,000 kilometers. For ordinary nickel alloy spark plugs, replacement is recommended every 20,000 kilometers, while iridium spark plugs can last between 60,000 to 80,000 kilometers before needing replacement. Under normal maintenance conditions, spark plugs should be replaced when the vehicle has traveled 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine type, so it is advisable to refer to the owner's manual for specific recommendations. Steps for replacing spark plugs: Open the engine hood and remove the plastic cover of the engine. Disconnect the high-voltage ignition wires, marking each cylinder's position to avoid confusion. Use a spark plug socket to remove the spark plugs one by one. During removal, check for any external debris like leaves or dust and ensure the area is clean. Insert the new spark plugs into the spark plug holes, hand-tightening them first before using the socket wrench to secure them. Reinstall the high-voltage ignition wires in the correct firing order, then reattach the cover.
