How Often Should the Spark Plugs of Arrizo 7 Be Replaced?
2 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.
