Magotan's spark plugs should be replaced every 30,000 kilometers. Methods to determine if spark plugs are damaged: Remove the spark plugs for observation and assess their condition based on the following appearance colors. Normal spark plugs have insulator skirts and electrodes that appear gray-white, gray-yellow, or light brown. A properly functioning spark plug has a reddish-brown insulator skirt, an electrode gap between 0.8-0.9mm, and no signs of electrode burning. If the spark plugs are contaminated with oil or deposits but are not damaged, they can continue to be used after cleaning off the oil and deposits. If the spark plugs are severely damaged, with phenomena such as blistering at the top, black streaks, cracking, or electrode melting, the cause of the damage should be identified. After troubleshooting, replace the spark plugs with new ones. Additionally, if the spark plugs appear black as if smoked, it indicates that the wrong heat range was selected or that the air-fuel mixture is too rich, with oil seeping up.

I've been driving my Magotan for several years, and when it comes to spark plugs, you really need to check the manual. My suggestion is to inspect them every 30,000 to 40,000 kilometers and replace them around 60,000 kilometers. As spark plugs age, their ignition capability declines, which can make the car feel underpowered, sluggish during acceleration, and may even increase fuel consumption. Once, I delayed replacing them until 70,000 kilometers, and my fuel consumption rose by 10%. The car also took much longer to start in the morning—it was practically throwing money away. Don’t cheap out on low-quality spark plugs; just stick to OEM or reputable brands. If you’re handy, you can even pull them out yourself to check the electrode wear. Regular maintenance isn’t just about saving money—it keeps the car responsive and smooth, almost like driving a new car. After all, the Magotan’s engine is precision-engineered, and spark plugs have a significant impact on overall performance. Don’t wait for problems to arise before fixing them, because by then, repair costs will be much higher.

I often change spark plugs by myself and find DIY incredibly fun. For the Magotan, the spark plug replacement interval is generally between 40,000 to 60,000 kilometers, but you should always check the manual for specifics. I usually remove the ignition coils every six months to inspect the spark plug electrodes, and replace them immediately if I find excessive gap or signs of burning. The tools are quite affordable online—just a wrench, socket, and insulated gloves will do the job. But remember to turn off and cool the engine before starting, or you might burn yourself and cause an accident. Apply anti-seize compound to the new spark plugs and tighten them gently without over-torquing, as excessive force can damage the engine block threads. The type of spark plug affects its lifespan—iridium ones are pricier but last longer. After replacement, you’ll notice improved fuel efficiency and smoother starts. It’s a cost-effective and reassuring task, even for beginners, but always prioritize safety and avoid reckless actions.

Spark plug replacement should be considered from an economic perspective. My Magotan manual suggests inspection at 30,000 km and replacement at 60,000 km, but when these parts age, fuel consumption soars—costing you several extra yuan per kilometer. For instance, after I replaced my spark plugs at 40,000 km last time, I saved dozens of yuan in fuel costs within a month, making it a small investment with significant returns. Poor-quality spark plugs can cause misfires, leading to rough idling, sluggish acceleration, or even more expensive failures. Replace them on schedule—don't wait until the ignition coil burns out, as repair costs could double. Just choose a cost-effective spark plug brand; OEM parts may be pricier but more durable. Staying vigilant about your car's performance and addressing issues early is the most economical approach.
