How to Remove the Spark Plugs of a Sylphy?

Sylphy spark plug replacement steps: 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. While 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 a few turns, then use the socket to tighten it further. Reinstall the removed high-voltage ignition wires in the firing order and snap the cover back into place. Damaged spark plugs can directly cause issues such as ignition system leakage, increased fuel consumption, reduced power output, and most notably, difficulty in starting the vehicle, affecting its normal operation. Severe spark plug erosion—evidenced by pitting, breakage, or melted/burnt electrodes—indicates the spark plug is ruined and should be replaced.
Last time I changed the spark plugs on my Nissan Sylphy, it went pretty smoothly. After letting the engine cool down, I first disconnected the negative terminal of the battery to prevent short circuits or electric shocks. Then I located the ignition coils - those small components plugged on top of the spark plugs - and carefully pulled them out one by one. Using a 16mm socket wrench with an extension bar, I slowly turned counterclockwise to remove the spark plugs. Throughout the process, I was careful not to let any dust fall into the holes, having wiped the surrounding area clean with a dry cloth beforehand. After unscrewing and removing the old spark plugs, I checked that the new ones were the correct model before gently screwing them in, finally tightening them appropriately with the wrench without using excessive force. Doing it myself saved on labor costs, and the Sylphy's space design is quite user-friendly. However, for those not accustomed to car maintenance, I'd recommend watching a video tutorial first to avoid damaging the engine internals. Delaying spark plug replacement can lead to engine shaking and increased fuel consumption, so regular maintenance is quite important.
As a car enthusiast, I really enjoy DIY spark plug replacement. The spark plugs on the Nissan Sylphy are quite easy to remove. First, disconnect the negative battery terminal for safety. The ignition coils can be pulled straight out. Prepare a dedicated spark plug wrench with an extension bar, align it properly and turn counterclockwise to loosen. Be careful not to apply excessive force during operation to avoid breakage inside. The whole process takes just a few minutes per cylinder. The Sylphy's engine bay is spacious, so no deep reaching is needed. When installing new spark plugs, choose reputable brands and turn them in gently to prevent cross-threading. DIY is both fun and cost-effective. I recommend checking them every 30,000 km - worn spark plugs can affect starting speed and fuel efficiency.
