How Often Should the Spark Plugs of Arrizo 7 Be Replaced?
4 Answers
The spark plugs of Arrizo 7 should be replaced every 30,000 kilometers. The selection of spark plugs can be based on the engine's compression ratio to make the engine more stable, such as NGK spark plugs and ESE ignition wires, engine speed, and air-fuel ratio. High-compression ratio engines require spark plugs with high-temperature resistance, while low-compression ratio engines need spark plugs with correspondingly lower temperature resistance. The Arrizo 7 is a self-owned brand car of Chery Automobile. In terms of power configuration, it is equipped with a 1.6L DVVT engine, which can deliver a maximum power of 93 kW and a peak torque of 160 Nm, paired with a CVT continuously variable transmission independently developed by Chery.
I've been driving my Arrizo 7 for three years now, and it's safest to replace the factory spark plugs approximately every 30,000 kilometers. Just last week during my 4S dealership maintenance, the mechanic showed me the electrodes were completely burnt black. For those who frequently take long trips or enjoy flooring the accelerator, I'd recommend checking them as early as 25,000 kilometers. Never wait until the car develops ignition difficulties or idles as unevenly as a massage chair before replacing them - by then you might even damage the ignition coils. Nowadays, I have the mechanic check one cylinder's spark plug every 20,000 kilometers. After all, spending just three to four hundred yuan for spark plug replacement during minor maintenance is far more economical than a major engine overhaul.
Pro tip from an experienced driver: The regular copper-core spark plugs in an Arrizo 7 last about 30,000 km at most. My car is now 6 years old, and every time it hits just over 30,000 km, the fuel consumption noticeably increases, and the tachometer needle dances like crazy at idle. Don’t rigidly follow the manual’s recommendations—consider your driving conditions too. For someone like me, crawling through city traffic every day to drop off and pick up kids, the spark plugs wear out faster. Last time, I took advantage of a dealership promotion and got a set of platinum spark plugs for 268 RMB, including labor. Now, at 50,000 km, they’re still performing well. Remember, always replace the entire set of spark plugs—don’t cheap out and leave a couple of old ones in the cylinders to cause trouble.
The replacement interval for spark plugs depends on their material. The original standard nickel alloy spark plugs in the Arrizo 7 can last up to 30,000 kilometers at most. If upgraded to premium materials like platinum or iridium, they can endure 60,000 kilometers. My car was fitted with double iridium spark plugs, which lasted 70,000 kilometers before replacement, with the electrode gap not exceeding 0.1mm. Daily driving habits are crucial: frequent short trips are most damaging to spark plugs, as multiple cold starts are required to reach operating temperature, leading to carbon buildup on the electrodes. Remember to have the technician measure the electrode gap during every 20,000-kilometer maintenance; if it exceeds 0.8mm, it's time for a replacement. After replacement, the acceleration noticeably improves, giving an old car a second lease on life.
