The oil filter is an engine component of a car, specifically a key component in the engine lubrication system. Its function is to remove impurities such as metal debris and carbon particles from the oil by filtering, keeping the oil clean and thus protecting the normal operation of the engine.

The air filter is a component of the car's engine system and one of the "three filters" of the engine. Its main function is to filter out dust, particulate matter and other impurities in the engine's intake air to prevent them from entering the cylinder and causing wear, thereby protecting the engine's core components and extending their service life.

Brake pads are key consumable components in a car's braking system (brake system). They convert the vehicle's kinetic energy into heat energy through friction with the brake disc or brake drum, thereby slowing down and stopping the vehicle.

The ignition coil is a core component of a car's engine and ignition system. It converts the vehicle's low-voltage electrical energy into high-voltage energy, igniting the mixture in the cylinder through the spark plug, thereby driving the engine.
