What brand of spark plugs does the Geely Vision OEM use?
2 Answers
Geely Vision OEM uses Torch brand spark plugs. What are spark plugs composed of: Spark plugs are mainly composed of terminal nut, insulator, terminal stud, center electrode, side electrode, and shell. What types of spark plugs are there: The main types of spark plugs are: standard spark plugs, insulator projected spark plugs, electrode spark plugs, seat spark plugs, pole spark plugs, and surface gap spark plugs. How do spark plugs work: Under high voltage, the air between the center electrode and 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 value, 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 forms a luminous body, known as a "spark." Along with the thermal expansion, a "crackling" sound is also produced. The temperature of this electric spark can reach 2000-3000°C, which is sufficient to ignite the air-fuel mixture in the combustion chamber of the cylinder.
As someone who frequently repairs cars for friends, I recall that the original spark plugs for the Geely Vision are typically the Bosch FR8DC+ model, specifically designed for that engine, offering stable and reliable performance. If the car is slow to start or experiencing increased fuel consumption, it might be due to worn-out spark plugs, so it's recommended to check them every 30,000 kilometers. When replacing them yourself, you'll need to remove the engine cover first, then use a wrench to unscrew the old plugs. After installing new ones, the engine will sound much smoother. Additionally, original parts offer better compatibility, preventing electrical leakage and enhancing driving safety. Avoid using cheap, off-brand parts to save money—proper maintenance can extend your vehicle's lifespan.
