It’s easy to forget about important technical aspects such as engine filters during regular day-to-day driving. Engine filters work to keep the engine free from debris and pollutants. Over time a car’s filter will always get dirty. Dirty air filters restrict airflow into the engine, eventually hurting a vehicle’s performance. As a responsible owner, it’s important to be aware of signs that indicate an air filter is faulty. Maintain optimal engine performance by keeping your engine free from pollutants. Below is a list of common symptoms the engine air filter should be replaced.
A Decrease in Engine Power
Each drive sucks in contaminated air, and engine filters prevent debris, dust, dirt, and bugs from entering the engine. If the air filter isn’t regularly changed, the filter will become clogged. A clogged prevents an adequate amount of air from getting into the engine. This will lead to the engine running less efficiently than it should. Poor acceleration is a telltale sign of a dirty air filter. A clogged air filter can be prevented by changing your air filter every 12,000 miles or so, depending on driving habits.
The Engine Misfires
A dirty air filter decreases the amount of air supplied to the engine. This can lead to an increase in unburned fuel that turns into soot residue. Soot can mound up on the spark plug tips making them unable to deliver a proper spark. In return, the car can jerk, idle, and in some circumstances, the engine can misfire.
Weird Engine Noises
If a car is idling, the engine should give a typical hum. A clogged air filter limits air supplied to the combustion chamber. The combustion chamber, in turn, can sputter, pop, or give cough-like sounds. Odd sounds may also be accompanied by vibrating or shaking.
Reduced Fuel Efficiency
Gasoline and air work together to power the engine. Contaminated air filters provide insufficient air, so the engine ends up using more fuel to overcompensate. A noticeable decrease in gas mileage can indicate a bad air filter.
The Engine Filter Looks Dirty.
You can determine an air filter state by popping the hood and giving it a visual inspection. Most Air filters are white. If they’re clean and you illuminate them with a flashlight, you should be able to see through it. Faulty air filters will visibly look caked, clogged, and contaminated
