What are the consequences of not replacing the air filter?

Consequences of not replacing the air filter: Dust and other particles can enter the engine, causing wear and tear on the cylinders and components. During operation, the engine draws in a large amount of air, which passes through the air filter to prevent suspended particles from entering the cylinders, thereby protecting the pistons and cylinders from wear. Without an air filter, these particles entering the cylinders and pistons can cause severe cylinder scoring. Thus, the air filter plays a crucial role in filtering air, dust, and particles within the engine. The air filter is a core component of engine filtration, classified as a consumable part that requires special maintenance and care. Without it, particles entering the cylinders and pistons can lead to severe cylinder scoring. Therefore, the air filter ensures that only clean air enters the cylinders, protecting the engine from damage.
As a seasoned driver with over a decade of experience, I must emphasize the serious consequences of neglecting air filter replacement. When the engine can't intake sufficient air, you'll notice significant power loss during acceleration – the car responds sluggishly like an ox-drawn cart, especially when climbing hills or overtaking on highways. Fuel consumption also stealthily increases, costing you dozens extra per month as the fuel gauge drops alarmingly fast. Dust particles seize this opportunity to invade the engine interior, wearing down piston rings and cylinder walls. Over time, this shortens engine lifespan, with repair bills easily exceeding tens of thousands. A friend of mine learned this the hard way – his clogged filter eventually damaged the mass airflow sensor, leaving the check engine light permanently on. Replacing filters is simple and inexpensive (just tens of RMB), yet it rejuvenates your car's performance and prevents major overhauls. I now personally inspect mine every 10,000 km, replacing immediately when dirty – protecting my engine while saving both hassle and money.
I usually drive to work and have noticed that delaying the replacement of the air filter can severely degrade my car's performance. The power output becomes unstable, acceleration response slows down, and it's even difficult to keep up with traffic in congested areas. Fuel consumption increases while mileage decreases. Once the filter fails, dust enters the engine, causing incomplete combustion, emitting black smoke or unpleasant odors, which significantly harms the environment. Internal parts wear out faster, potentially leading to more expensive repairs in the long run, such as sensor failures or valve issues. I make it a habit to replace the air filter during every six-month maintenance, costing less than a hundred bucks, and the performance immediately returns to smooth operation. This small action saves fuel, is eco-friendly, and avoids unexpected expenses.
