The engine air filter is a vital component that filters dirt and debris from the air entering your engine. It helps keep your engine running cleanly and efficiently.
Today, I want to go over some of the common symptoms that indicate your car's air filter needs to be replaced. A dirty or clogged air filter can cause a variety of problems, so being able to recognize when it needs to be swapped out is important.
What is an air filter? The air filter is usually a pleated paper or fabric cartridge that sits inside a plastic or metal housing connected to the engine air intake system.
As air passes through, the filter captures dust, pollen, smoke and other pollutants before they can enter the engine. This keeps your engine internals clean.
When to replace? Most automakers recommend inspecting your engine air filter at every oil change and replacing it as needed or at least once a year. Shorter intervals may be required if you drive in very dusty or polluted conditions regularly. An extremely clogged filter should be replaced immediately.
Symptom 1: Decreased engine performance...
Symptom 2: Higher fuel consumption...
Symptom 3: The check engine light comes on...
Symptom 4: Strange smells from the vents...
Symptom 5: Engine surging or misfiring...
Replacing a dirty air filter is one of the easiest and most important maintenance tasks for your vehicle.
Catching a clogged filter early helps maximize engine performance and fuel economy. Let me know in the comments if you've experienced any of these air filter issues!

Thanks for sharing this. Can it trigger a P0420 code?

No that’s your catalytic converter.

can it trip a rich code

Hi, Yes, a dirty engine air filter can restrict airflow to the engine, causing the air-fuel mixture to become richer than normal. When there's insufficient air, the oxygen sensors detect a rich condition, and this can trigger a rich code. The engine control unit (ECU) may attempt to compensate for the restricted airflow by adjusting fuel delivery, leading to a persistent rich condition if the air filter is excessively dirty. Replacing the air filter can often resolve this issue.

Can it cause the car to switch off immediately after you put ut on??Thx

Yes

Hi, A severely clogged air filter can potentially cause a car to turn off shortly after starting, though it's a less common cause for such a symptom. The air filter is crucial for providing clean air to the engine; when it's extremely dirty, it can restrict the airflow. This restriction might lead the engine to receive an improper air-fuel mixture, making it difficult for the engine to run properly, especially just after starting when the engine might be more susceptible to performance issues. However, if a car turns off immediately after starting, other issues are often more likely to be the cause. These can include problems with the fuel system (like a failing fuel pump or dirty fuel injectors), issues with the ignition system (such as faulty spark plugs or ignition coils), or even electronic problems like sensor malfunctions.

I do have dry eyes. Will the dirty air filter gets my eyes to act up?

Hi there, You many need to change the cabin air filter (also known as Pollen Air filter) frequently. The engine air filter is designed to prevent dirt, dust, and other contaminants from entering the engine's intake system. Clean air is crucial for the engine's combustion process, as it ensures the right air-fuel mixture for efficient performance.
