What material is the Geely Emgrand spark plug made of?
2 Answers
Geely Emgrand spark plugs are made of NGK Japan's iridium LZFR6AI3656. Spark plugs are installed on the side or top of the engine. In the early days, spark plugs were connected to the distributor via ignition cables. Over the past decade, most car engines have been modified to connect the ignition coil directly to the spark plug. Steps to replace spark plugs: Open the hood, lift the engine's plastic cover, remove the high-voltage ignition cables, 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 any external debris like leaves or dust and make sure to clean them thoroughly. Place the new spark plug into the spark plug hole, hand-tighten it a few turns, and then use the socket to tighten it further. Reinstall the high-voltage ignition cables in the firing order, then snap the cover back into place.
When I used to drive a Geely Emgrand, the spark plugs were made of nickel alloy, a pretty common and economical choice. Nickel alloy spark plugs are low-cost but don’t last very long, typically requiring inspection or replacement every 30,000 to 40,000 kilometers. The role of spark plugs is to ignite the air-fuel mixture—once the material degrades or wears out, ignition becomes unstable, which can lead to engine misfires, increased fuel consumption, or even difficulty starting. I remember changing them once and also checking the ignition coils at the same time. During regular maintenance, I’d ask the mechanic to quickly inspect the spark plug gap and keep them clean. Upgrading to platinum or iridium spark plugs would offer better durability, but for a car like the Emgrand, nickel alloy is perfectly adequate—the key is that I never had any major issues. If left unchanged for too long, the engine light might come on, leading to unnecessary repair costs. Overall, following the manual for scheduled maintenance gives much more peace of mind.
