Haval M6 spark plugs should be replaced approximately every 40,000 kilometers. Under normal maintenance conditions, spark plugs are typically replaced between 40,000 to 60,000 kilometers of driving. However, this may vary depending on the brand and engine type, so it's recommended to follow the user manual. The following standards can be referenced 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 60,000-80,000 kilometers. Spark plug replacement steps: Open the hood, lift the engine's plastic cover, remove the high-voltage distributor wires, and mark each cylinder's position to avoid confusion. Use a spark plug socket to remove the spark plugs one by one. During removal, check for any external debris like leaves or dust, and ensure everything is cleaned thoroughly. Place the new spark plug into the spark plug hole, hand-tighten it a few turns, and then use the socket to tighten it further. Reinstall the removed high-voltage distributor wires according to the firing order, and then secure the cover plate.

I've been driving a Haval M6 for over two years now. Although spark plugs may seem small, they have a significant impact on the engine. The official manual recommends replacing them every 30,000 kilometers or every 2 years, but the actual replacement interval depends on driving habits. For example, since I often encounter traffic jams in the city, spark plugs are more prone to carbon buildup, and replacing them early can prevent ignition issues. I remember the last time I delayed replacement, the car started slowly, fuel consumption increased sharply, and it even stalled once on the road. After installing new ones, the power noticeably improved. I recommend everyone check them according to the mileage and not wait until the car shakes or has poor acceleration to deal with it. Spark plugs aren't expensive; getting them replaced at a 4S shop costs just a few hundred yuan. Replacing them early saves trouble and money, and can also extend the engine's lifespan.

I always believe that car maintenance should pay attention to details. Although spark plug aging seems minor, it may cause major problems. The Haval M6 recommends replacing spark plugs every 30,000 kilometers, but if driving on rough roads or in dusty areas, the replacement interval should be shortened. Last time, I saw excessive carbon buildup on the spark plugs but didn't replace them in time, which resulted in engine misfires, sluggish acceleration, and excessive emissions. Early replacement ensures driving safety—don't wait for a breakdown like I did to regret it. Choosing platinum spark plugs can offer better durability. The cost of replacement is low but the benefits are significant, and most importantly, it doesn't affect overall performance.

Spark plug replacement isn't just about following the manual. From an economic perspective, the Haval M6's standard is to replace them every 30,000 kilometers. While ordinary spark plugs are cheaper, they have a shorter lifespan. Switching to iridium ones costs more but lasts longer. Last time I delayed replacement, my fuel consumption increased by 10%, making the extra fuel costs not worthwhile. Failed spark plugs might damage the ignition coil, leading to even higher repair costs. Therefore, timely replacement is the wisest choice, ensuring both vehicle economy and avoiding additional losses.
