How many kilometers does the Baojun 730 need to replace the spark plugs?
2 Answers
Baojun 730 requires spark plug replacement every 40,000 kilometers. Spark plugs, commonly known as sparkers, function by discharging the pulsed high voltage electricity sent from the high-voltage wires (sparker wires), breaking down the air between the two electrodes of the spark plug to generate an electric spark, thereby igniting the air-fuel mixture in the cylinder. The Baojun 730 is a family MPV product under the SAIC-GM-Wuling Baojun brand, with body dimensions of 4780mm in length, 1820mm in width, and 1755mm in height, and a wheelbase of 2750mm. In terms of exterior design, the rear styling of the Baojun 730 has undergone significant adjustments, with reduced chrome strips and an enlarged tailgate that spans the entire horizontal width of the rear. The tail lights have been redesigned from a split-type to a one-piece design, featuring sharp styling and a horizontal LED light strip that is fashionable, eye-catching, and exudes a sense of technology.
I've been driving my Baojun 730 for several years and typically replace the spark plugs every 40,000 kilometers. I remember when my car had just over 40,000 km on it, the startup began to feel sluggish, the engine occasionally shook, and fuel consumption noticeably increased a bit. I took it to the repair shop, and the technician said the spark plug electrode gap had widened, affecting ignition. After replacing them with a new pair of standard nickel-alloy spark plugs, which cost less than 200 yuan, the car immediately regained its power, acceleration became smooth, and fuel consumption returned to normal. I recommend Baojun owners not wait for issues to appear before replacing them; instead, regularly check the spark plugs' condition at around 30,000 km to see if there's any carbon buildup or wear. For city driving with frequent stops, wear might be faster, so preventive maintenance based on mileage is the safest approach. Also, during maintenance, check other ignition components to avoid related issues—don't skimp on small problems that could escalate into major repairs.
