What happens if the engine air filter is not replaced?
2 Answers
If the air filter is not replaced for a long time, it will accumulate dust and other debris, which will affect and obstruct the flow of air in and out, thereby also affecting the engine's air intake. For detailed information, please see below: 1. The disadvantages of not replacing the air filter for a long time: Prolonged failure to replace it will impact the engine and increase fuel consumption. The correct replacement interval for an air filter is approximately 20,000 kilometers, but it can also be adjusted based on different cities. The maintenance cycle at a 4S shop is generally 10,000 kilometers or 8,000 kilometers, so it can be considered to replace it every two cycles. 2. Regional factors: For vehicles in the northwest region, due to reasons like dust, air quality can change significantly. If you frequently drive during this period, earlier replacement is necessary. Besides dust, the dust particles in the northwest are different from those in the south, so the impact can be greater.
Not changing the engine air filter is really troublesome. I once ignored it for a few months, and as a result, air couldn't get in, making the engine struggle to breathe. The combustion efficiency dropped, the car accelerated like a turtle crawling, and fuel consumption skyrocketed. Impurities entering the engine wore down the cylinder walls, leading to high repair costs in the long run. A clogged filter also affects emissions, causing black smoke from the exhaust, which is bad for the environment. Driving in the city means more dust, so it's essential to check it regularly and replace it every 10,000 kilometers or once a year. This small part costs just ten bucks to replace, saving you from spending a fortune on major repairs—I learned this the hard way.
