What is the spark plug model for the Baojun 630?

[Joel]

The NGK platinum spark plug model for the Baojun 680 is DCP7REGP, and the Torch iridium spark plug model is DK7RIU. Main types of spark plugs include: standard spark plugs, extended insulator spark plugs, electrode-type spark plugs, seat-type spark plugs, pole-type spark plugs, and surface-gap spark plugs. Spark plug replacement cycle: Under normal maintenance conditions, replacement is recommended after driving 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine, so it's advisable to follow the user manual. 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: Under high voltage, the air between the center electrode and the side electrode of the spark plug rapidly ionizes, forming positively charged ions and negatively charged free electrons. When the voltage between the electrodes reaches a certain level, the number of ions and electrons in the gas increases like an avalanche, causing the air to lose its insulating properties and forming a discharge channel, resulting in a "breakdown" phenomenon. At this point, the gas becomes a luminous body, known as a "spark." Along with the heat expansion, a "crackling" sound is also produced. The temperature of this electric spark can reach 2,000-3,000°C, which is sufficient to ignite the air-fuel mixture in the cylinder combustion chamber.

The original spark plug model for the Baojun 630 is usually NGK BPR6EY. I confirmed this by checking my own 2014 model, and the mechanic also verified it during repairs. Earlier models like the 2012 version might use BPR5EY-11, which has a different heat range. When buying replacements, don't just focus on the brand; a heat range parameter around 7 degrees is safest, with a thread diameter of 14 mm. Don't overtighten when installing, and use a 16mm socket wrench. Avoid off-brand plugs often recommended by roadside shops, as their electrodes wear out quickly and can cause shaky cold starts. Searching for 'Baojun 630 original spark plug' on JD.com usually yields matching options. Remember to clean electrode carbon deposits during replacement and avoid touching the ceramic part with oily hands.

Having repaired cars for over a decade, the Baojun 630 commonly uses just three types of spark plugs: NGK's BPR6EY, Champion's RC7YC, and Bosch's FR7DC+. Models manufactured after 2015 mostly use NGK's nickel alloy electrode variant—checking the engraving on the old part is the most accurate method. Key specs for the spark plugs include a heat range of 6-7, thread length of 19mm, and recommended ignition gap adjustment to 0.8mm (too wide causes rough idling). When replacing them yourself, avoid yanking the ignition coil connector—use specialized rubber sleeve pliers to prevent electrical leakage. Aftermarket parts often skimp on electrode materials, potentially increasing fuel consumption by half a liter per 20,000 km driven.

Veteran driver's hands-on experience: For the 2011-2014 Baojun 630 models, use NGK BPR5EY spark plugs. After the 2015 facelift, most switch to BPR6EY. Learned the hard way by buying wrong models at hardware stores – once mistakenly used K6RTC plugs and experienced noticeable power lag on highways. Nickel alloy plugs must be replaced every 30,000 km, while iridium ones can last 60,000 km, but don't blindly trust extended lifespan – it's useless on carbon-fouled engines. Recommend keeping a T-handle socket wrench handy; DIY replacement takes just half an hour, totally not worth paying 80 bucks labor at repair shops.

Maintenance Manual Excerpt: The Baojun 630 requires spark plugs with a heat range of 6-7 and thread specification M14×1.25. The original NGK BPR6EY costs approximately 26 yuan per piece, while the Bosch FR7DPP30 platinum alternative offers better durability. Always disconnect the negative battery terminal before starting! Use a magnetic pickup tool during installation to prevent dropping parts into the cylinder, and do not exceed 25 N·m of torque. For modified vehicles, the Denso IK20 iridium plug is an option, but the gap must be manually adjusted to 0.9mm to avoid triggering the check engine light. Inspecting old plugs: white deposits indicate a lean fuel mixture, while black deposits signal carbon buildup warning.

Auto Parts City Tips: The 630 spark plug universal models are divided into three categories. The 1.0L engine uses BPR5ES, the 1.5L naturally aspirated engine comes standard with BPR6EY, and the 1.8L version is compatible with ILTR5A-13G. The most accurate way to determine is by checking the engine number on the vehicle's nameplate: choose heat value 5 for LZW prefixes, and heat value 6 for L2B engines. When shopping online, look for 'Special for Baojun 630', and be cautious of those priced below 20 yuan, as the electrode copper core is as thin as paper. During major maintenance, also check the cylinder wires, as aging and cracking can cause new spark plugs to be punctured.
