An Engine air filter is that little component in your car which provides fresh and filtered air to your car’s engine.
You can think of it as lungs of a car whose job is to clean the atmospheric air from dust particles or other contaminations before it goes into the engine, which you can assume as the car’s heart. So that is to say that air filters are very important for your vehicle to run efficiently. The air filter is a little piece of foam-like material which is permeable for air only and traps dust and debris and prevents it from getting into the combustion chamber. The filter resides in a box called the filter box, which keeps the filter in position, directly above the air intake hose. With time, air filters can get dirty due to the outside air filled with dust and other particles in the air. In that case, your car will not perform as efficiently as it should and this means it’s time to either clean the filter or replace it.
Although cars come fitted with OEM filters, there are lots of high-quality aftermarket filters which can boost the performance of your car. We have done the hard part of gathering information about the best air filters out there for you to choose from.

Air Filter FAQ & Info
Which filter is right for my car?
If you don’t know already, a car’s engine relies on a lot of things to work but out of all those things, 2 major things stand out, one of which is fuel and the other being air. The mixture of the two is what makes your engine work and as a result make the car move. Just as clean fuel is important for your engine, same goes for air which is why car makers include an air filtration system in the first place. All that being said, the answer to which filter is good for your car is simple.
The function of an air filter is rather simple although really crucial. To filter air. Normally, we don’t see the dirt in air but rather we feel it in the eyes. Air contains tiny dust particles from the atmosphere and although tiny in size, can greatly influence the mixture and car’s performance if it gets into the combustion chamber. Your car will not only face decreased performance but also engine wear which can cost you big in the long run.
That being said, the answer to which filter is best for your car is simple. The functions cannot vary but only the quality and price. The purpose for any filter is one. To clean the air for your car. The best filter for your car is the one that fits your filter box perfectly.
Do aftermarket air filters really make a difference?
Yes, aftermarket air filters really do make a difference as they are made purposely. Most of them include some kind of unique technology or filters which do the job betters than OEM filters
Does frequent air filter change improve engine life?
Yes. As outside air is never really clean, dirt can build up overtime and clog the filter which can directly impact the amount of air coming in the engine. That will affect the performance and mostly the gas mileage as the air-fuel mixture wouldn’t be proportional. By frequently and timely cleaning the air filter, you can ensure top performance by your engine and long life of your filter.
How do air filters affect emissions?
When air flow is restricted, more of gasoline will burn and the emission which contain more fuel than air which is a big pollutant of air. Modern cars are equipped with a computer which decides how much fuel to add according to air. If air is restricted, fuel will be restricted and so will performance.
What are the signs which tell that my air filter needs replacing?
Normally, vehicle manufacturers suggest to change the air filters after every year or 12,000 miles but that is subject to car usage and area where the car is driven. If driven in sandy areas, the filter might clog up quickly and need to be cleaned or replace quicker. Different filter brands also vary in the amount of time before the filter needs to be changed. Here are a few signs you can look for to know if it’s time to change the filter or not:
The appearance of the filter
The first and most obvious sign is a dirty or blackened air filter. If upon inspection, you find that your filter is simply dirty, it is time to clean it. If your air filter is very old, it may be time to change it altogether and replace it with a new one.
Reduced Fuel Economy
Another sign is a decrease in mileage. If you realize that your car is using more gasoline than it used to, it may be due to a bad air filter. In that case, inspect your air filter to see if it’s dirty. It may also be torn.
Exhaust Producing Black Smoke
You start your engine and find out that black smoke is coming out of the tail pipe. Although this could be due to many different reasons, one of the reason is a bad air filter. That happens if your car isn’t getting enough air to burn with fuel.
Rough Noise with the aid of the Engine
If you air that your car makes a ‘whiff’ sound as you step on the gas, that’s a sign that your engine is having a hard time getting air. That’s a sure sign that your air filter is blocked and restricting air flow.
How can I change/clean the air filter on my car myself?
Changing the air filter is as easy as cleaning your vacuum cleaner at home. Here’s a step by step guide to clean your car’s air filter:
Open Hood and Find the Filter Box
The air filter box is easy to find in almost every vehicle. It is usually right above the spark plugs or on the right in the engine bay. The filter is fitted inside a box which is either clipped or tightened with screws. Unclip the top part of the box and take the filter out. Check for any damage. If it’s good, you can just clean and it put it back in.
Cleaning the filter
Some filters can be cleaned simply by tapping them to remove the dust over the filter. To thoroughly clean the filter, you will need to wash it with a soap or detergent. Although you should refer to the owner’s manual if you are cleaning your OEM filter. If you are cleaning aftermarket filter, refer to the instructions given by the manufacturer of the aftermarket filter to not damage the filter.
Install New Air Filter
If you suspect any damage whatsoever, it’s time to change the filter. The new filter will be of the same size and dimensions as the original one and all you need to do is take the old one out and replace it with the new one whether its OEM filter or an aftermarket one
Buying the Correct Air Filter
Buying the correct air filter means buying the right size for your filter box. If your new filter isn’t fitting your filter box, it’s wise to not forcefully install it as it will be useless to do so. A filter box is tightly sealed which serves the actual purpose of filtration. Air is gathered in bulk amount and accumulated in the box. The outside force pulls the air in the engine but as the air is being pulled, the air needs to pass through the filter itself which decontaminates air before it can get to the combustion chamber. There is no space inside the filter box from where the air can leak out or can be let in. If that were so, dirty air could get inside your engine and render your filter useless.
The deal with air filters is actually very straightforward. Air filters are one of the important components in your car whose function may be simple but is very important in the efficient working of the engine. Air filters are inexpensive so you don’t need to worry too much about replacing them frequently. But because of technology, even that has added benefits. Air filters, especially aftermarket ones, are now more rigid and long lasting. Some work for as long as 100,000 miles. Besides that, modern filters can be reused and cleaned multiple times to take away the hassle of replacing them frequently.
With all that in mind, maintenance of air filters should not be overlooked as, saving a few bucks on filters could lead to having you spend a big amount on engine repairs due to failure of parts and air sensors. Not only that but you will face low performance by your car.
