[PresleyFitz]

The original spark plug for the Lavida 1.6L is from the BOSCH brand, with the model number F7HER-2. Depending on the vehicle model and production batch, the specific model number of the spark plug used may vary slightly. The spark plug is a crucial component of the gasoline engine's ignition system. It introduces high-voltage electricity into the combustion chamber, causing it to jump across the electrode gap and create a spark, thereby igniting the combustible air-fuel mixture in the cylinder. It mainly consists of a terminal nut, insulator, terminal stud, center electrode, side electrode, and shell. Spark plug replacement cycle: Under normal maintenance conditions, replacement is recommended every 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine type, so it's advisable to follow the owner's manual. You can refer to the following standards for maintenance and 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 to 80,000 kilometers.
