What is the most commonly replaced car part?

In the daily use of a car, some parts are like the socks or shoe soles we wear – they are "consumables" that must be replaced regularly. If we had to choose the car part that needs replacing most frequently, it would definitely be filters and wear-and-tear parts.

▶Ranking of the Most Frequently Replaced Car Parts

▸Oil Filter

Simple explanation: If engine oil is the blood of a car, then the oil filter is the car's "kidney." Every time you go to the shop for basic maintenance (oil change), this car part must be replaced. It is responsible for filtering out impurities in the lubricating oil, protecting the engine from wear and tear. Because of its extremely short replacement cycle, it is one of the best-selling new parts worldwide.
Keywords: Basic maintenance, filtering impurities, essential replacement part.

▸Wiper Blades

Simple explanation: This is the car part that ages most easily. Because wiper blades are made of rubber, they are constantly exposed to wind, sun, and rain, and will harden and crack after a short time. If you notice that they don't wipe the water cleanly, or if there's a harsh friction sound when wiping, you need to replace them. This is also one of the parts that car owners most often replace themselves.
Keywords: Rubber aging, clear visibility, DIY replacement.

▸Air Filter

Simple explanation: The engine needs to inhale a large amount of air when it's working, and the air filter is its "mask." If you live in a dusty area, this car part will quickly turn black and become clogged. To make the car run more powerfully and fuel-efficiently, regularly replacing the air filter is common sense for every car owner.
Keywords: Engine breathing, dust protection, regular replacement.

▸Brake Pads

Simple explanation: Every time you step on the brakes, you are actually "wearing down" this part. Brake pads slow the car down through friction, and they must be replaced when they wear thin. Although they don't need replacing as often as filters, among all safety-related car parts, they are the fastest-wearing and most frequently replaced.
Keywords: Friction wear, driving safety, braking system.

▸ Car Battery

Simple Explanation: Many people might think car batteries last a long time, but in reality, they are the most frequent reason for roadside assistance calls to repair shops. Especially after a few years of use, or in extremely cold or hot weather, this car part can suddenly fail. It is crucial for ensuring your car starts smoothly.
