How many kilometers can the original spark plugs of Octavia last?
2 Answers
The original spark plugs of Octavia can last about 40,000 kilometers. Under normal maintenance conditions, spark plugs should be replaced after driving 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine, so it is recommended to follow the user manual. You can refer to the following standards for maintenance and replacement: Platinum spark plugs should be replaced at 40,000 kilometers, ordinary nickel alloy spark plugs at 20,000 kilometers, and iridium spark plugs at 60,000 to 80,000 kilometers. Steps to replace spark plugs: Open the engine hood, lift the plastic cover of the engine, and remove the high-voltage ignition wires. Mark the position of each cylinder to avoid confusion. Use a spark plug socket to remove the spark plugs one by one. Pay attention to whether there are leaves, dust, etc., on the outside and clean them thoroughly. Place the new spark plugs into the spark plug holes, hand-tighten them a few turns, and then use the socket to tighten them. Install the removed high-voltage ignition wires in the firing order and snap the cover back on.
I've owned a Skoda Octavia for several years now, and the original spark plugs lasted me about 80,000 kilometers before I felt the engine getting rough at low speeds. Spark plugs are tiny but vital; they control ignition in the engine, and for the Octavia, factory ones are often platinum or iridium types, designed to handle 60,000 to 100,000 kilometers on average. Driving style makes a big difference—aggressive acceleration in city traffic wore mine down faster than highway cruising. I learned to check them every 40,000 kilometers during routine services to spot early signs like reduced fuel efficiency or misfires. If you wait too long, it can lead to pricier fixes like catalytic converter damage, so I swap mine out every 7 years to keep things smooth and reliable on the road.
