What causes a clogged air filter?
Friday 5th April 2024
An air filter is a part that gets overlooked but can cause issues with your car’s performance. The filter acts as a barrier that prevents dust and dirt from entering the engine while allowing clean air to flow into the internal combustion chamber. Formula One Autocentres explores what can happen if your vehicle’s air filter is clogged.
Reduced mileage
If you notice that your fuel doesn’t seem to last, it may be due to a clogged air filter. If your car’s air filter is dirty, it reduces the airflow to the engine, thus reducing fuel efficiency. Therefore, if there is a notable decrease in fuel economy it may be time to replace your air filter.
You hear strange engine noises
Over time, your car’s air filter accumulates dirt, thus creating a vacuum inside the engine. When you start the engine, you may hear strange noises as it tries to get more air into the chamber for combustion. This in turn makes it difficult for the air to reach the petrol or diesel, thus flooding the engine.
A misfiring engine
Have you noticed that your car struggles to start whenever you turn it on? You may have a misfiring engine. A clogged air filter could be why your car’s engine is misfiring, thus leading to:
- Loss of acceleration.
- Poor performance.
If you have noticed a clogged air filter in your car, you should get the filter replaced immediately. Book your next fuel-saver service with Formula One Autocentres, and we’ll check your air filter to see if it’s causing your engine to misfire.
Check if the engine light comes on
A common sign that you have a clogged air filter is when the engine light comes on, signalling a fault with the engine. If you find the engine light stays on, it may be a signal to get the filter cleaned or replaced.
Reduction in horsepower
Does your car’s engine struggle to accelerate when you put your foot on the gas pedal? You may have less horsepower from the engine as it struggles to channel air into the combustion chamber. If you are pressing the accelerator harder than usual, it could signal a clogged air filter.
What should a healthy car air filter look like?
Usually, a healthy air filter should be light white and free from contaminants. Over time, if your filter turns darker in colour, you should get the filter replaced with a new one.
How often should my car’s air filter be replaced?
Ensuring your engine’s air filter is replaced periodically is crucial for your car to run efficiently and smoothly. We recommend getting your air filter replaced every 15,000 to 30,000 miles.
