How often should the spark plugs of Baojun 730 be replaced?

Baojun 730 spark plug replacement cycle: Under normal maintenance conditions, replacement is required after driving 40,000 to 60,000 kilometers. However, due to differences in brands and engines, it is recommended to follow the user manual. You can refer to the following standards for maintenance 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. How spark plugs work: The spark plug's ground electrode is connected to the metal shell, which is threaded into the engine block via the cylinder head. The insulator primarily serves to isolate the metal shell from the central electrode. The terminal nut is the part of the spark plug that contacts the high-voltage coil. When current passes through the terminal nut and the central electrode, it breaks down the medium between the central electrode and the ground electrode, generating a spark to ignite the air-fuel mixture in the cylinder.

The recommended replacement interval for the Baojun 730's spark plugs is generally every 30,000 to 40,000 kilometers, based on most owner's manual suggestions. Having driven this car for several years mainly for commuting, I've noticed that if spark plugs aren't changed for too long, the car tends to shake during cold starts, feel sluggish during acceleration, and fuel consumption increases significantly. Once I forgot to check on time, and the engine light came on while driving—it was really nerve-wracking. I suggest everyone get them inspected at a professional shop every 30,000 kilometers; different types of spark plugs affect lifespan, and the OEM ones are fairly durable. Additionally, city stop-and-go driving may shorten the interval. When replacing, clean the electrodes to save on fuel costs and prevent engine damage, extending the car's overall lifespan. Remember, regular maintenance not only saves hassle but also ensures driving safety.

Speaking of changing spark plugs for the Baojun 730, I learned from an experienced mechanic. The replacement interval is generally around every 30,000 kilometers, but it depends on individual driving habits—for example, frequent long-distance driving can stretch it to 40,000 kilometers. Worn-out spark plugs can cause engine misfires and emission issues, and in severe cases, repair costs can skyrocket. Last time, I replaced them myself—bought the same model online for less than 100 yuan, paired with a wrench, and the process was straightforward but required careful alignment. I recommend fellow drivers develop a habit of recording mileage and not wait until the car struggles to start before panicking. Using higher-quality gasoline in daily driving can also extend spark plug lifespan—money spent on maintenance is far more cost-effective than post-failure repairs.

The Baojun 730's spark plugs generally need replacement every 30,000-40,000 kilometers, depending on the spark plug type and driving conditions. Spark plugs function by transmitting ignition voltage to the air-fuel mixture for combustion. Once the electrodes accumulate carbon deposits or become worn, ignition efficiency decreases, potentially causing hard starts, power loss, and performance issues. I use iridium spark plugs, which have a longer lifespan than standard ones and can last up to 50,000 kilometers. Regularly visit a repair shop for diagnostic checks—it's cost-effective. Delaying replacement may lead to engine damage or even a significant increase in fuel consumption; the extra annual fuel costs could cover new spark plugs. Simple maintenance keeps your vehicle running efficiently.
