Where is the location of the spark plug on the Baojun 730?

Location of the spark plug on the Baojun 730: The spark plug is installed on the side or top of the engine. In earlier models, spark plugs were connected to the distributor via ignition cables, but over the past decade, most car engines have been modified to connect the ignition coil directly to the spark plug. How the spark plug works: The ground electrode of the spark plug 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 ionizes the medium between the central electrode and the ground electrode, generating a spark to ignite the air-fuel mixture in the cylinder.
I've worked on car repairs myself, and the spark plug location on the Baojun 730 is clearly visible, situated in the cylinder head area at the top of the engine. To access them, you'll need to open the hood, first removing the plastic decorative cover and some small components, as the spark plugs are covered by the ignition coils. For safety during replacement, it's best to disconnect the positive terminal of the battery. Then, unscrewing the coils will reveal the spark plugs. They're specifically located toward the front wheel side of the engine, making them easy to inspect but requiring professional tools for operation. I recommend regular checks and replacement every 30,000 to 40,000 kilometers to prevent ignition failure from affecting fuel efficiency. The location hasn't changed, and when doing it yourself, matching the correct spark plug model is crucial—refer to the user manual or online resources to avoid damaging the threads. In summary, the position isn't particularly hidden, but careful operation is needed. DIY can save money, but make sure you're familiar with the process.
