The spark plugs of the Trumpchi GS4 need to be replaced every 50,000 to 70,000 kilometers. This replacement interval is typically specified in the vehicle's manual as well. Below is the method for replacing the GS4 spark plugs: 1. Prepare the tools: a quick wrench, socket, and a Phillips screwdriver. 2. Unscrew the high-voltage terminal, clean the dust and oil around the high-voltage terminal, then use the socket to remove the fixing screw of the high-voltage terminal. 3. Remove the spark plug. After taking off the high-voltage terminal, use the socket to loosen the spark plug. 4. Install the spark plug. First, align the spark plug with the threaded hole using the socket, then gently screw it in by hand until about half of the thread length is engaged. Finally, tighten it with the socket.

I've been driving for over a decade and have replaced many spark plugs. The original spark plugs for the Trumpchi GS4 are made of standard nickel alloy, and the manufacturer recommends replacement at around 30,000 kilometers. If you frequently drive in congested urban areas, it's safer to replace them at 25,000 kilometers. Once, I delayed replacement by 5,000 kilometers and clearly felt reduced acceleration and increased fuel consumption. Nowadays, iridium spark plugs can last up to 60,000 kilometers, but don't opt for cheap, no-name brands to save money. During , remember to have the mechanic check the spark plug gap—excessive carbon buildup can affect ignition efficiency. Also, pay attention to whether the engine starts smoothly when cold, as this is a good way to assess the condition of your spark plugs.

My GS4 just had a full service, and the mechanic specifically reminded me about the spark plug issue. Standard copper-core spark plugs typically need replacement every 30,000 km, platinum ones can last up to 50,000 km, and double iridium plugs can go around 80,000 km. Recently, I noticed jerking when pressing the accelerator, which turned out to be carbon buildup and leakage in two spark plugs. Actually, by checking the oil stains on the spark plug threads and the wear on the electrodes, even regular car owners can judge whether they need replacement. It's recommended to have the 4S shop inspect them every 20,000 km. If buying spark plugs online, remember to match the heat range parameters. Last time, I tried to save time by replacing them myself but didn't tighten them to the proper torque, resulting in insufficient cylinder pressure.

The issue of spark plugs is not as simple as it seems, as it directly impacts fuel consumption and engine performance. My neighbor's GS4 didn't replace its spark plugs until 40,000 kilometers, only to break down midway. Nowadays, most auto repair shops recommend replacing standard spark plugs every 30,000 kilometers. If you notice black smoke from the exhaust pipe, idle shaking, or a sudden increase in fuel consumption, it's likely a spark plug issue. I make it a habit to remove and inspect one spark plug every six months for electrode wear; if the ceramic body shows cracks, it must be replaced immediately. Frequent short-distance driving tends to cause more carbon buildup, so it's advisable to replace spark plugs earlier for city commuter cars. Genuine OEM parts cost around a hundred yuan, which isn't expensive—don't wait until engine cylinder damage occurs to regret it.

Last time, the auto repair shop owner made a lot of sense when talking about spark plug lifespan. For the Trumpchi GS4, it depends on driving habits: those who frequently drive on highways can replace them at 40,000 km, while those often crawling in city traffic are advised to change them at 30,000 km. Ordinary nickel alloy spark plugs wear out faster, especially with frequent hard acceleration. I once saw a case where spark plug electrode erosion caused the ignition coil to puncture, tripling the repair cost. Now I use resistor-equipped spark plugs, which offer better protection for the fuel injection system. Listen to the engine sound during cold starts—if there's a delayed clicking noise, be alert. The manual's recommended interval is just a reference value.

Just experienced my first spark plug replacement, and it was quite an eye-opener. The Trumpchi GS4 manual recommends changing them at 30,000 kilometers, but in reality, it depends on your driving conditions. I commute 60 kilometers daily, and when I replaced them at 35,000 kilometers, the center electrode was already rounded from wear. The mechanic said if the electrode gap exceeds 1 millimeter, it's time to replace them, otherwise, the ignition energy will be insufficient. Now, with double iridium spark plugs, my fuel consumption has dropped by 0.5 liters, and cold starts are noticeably smoother. It's advisable to check for carbon buildup in the cylinders with a borescope every 20,000 kilometers. If there's oil on the spark plug threads, it might indicate a leaking valve cover gasket. Remember to disconnect the battery's negative terminal before DIY replacement.
