Does Changing Air Filter Improve Car Performance? - An Expert's Perspective

The most obvious benefit of changing your air filter is the greater fuel efficiency you'll get after replacing it. Because it improves air flow to the engine, your car doesn't have to work as hard, so it burns less gas. Increasing air flow to the engine can help improve overall vehicle performance. Replacing a clogged air filter can increase fuel efficiency and improve acceleration, depending on the make and model of your vehicle. When you realize that, it makes sense to replace air filters regularly.

How can an air filter make such a big difference? A dirty or damaged air filter limits the amount of air that enters the car's engine, causing it to work harder and therefore consume more fuel. Since the engine needs more than 10,000 liters of oxygen to burn each liter of fuel, it is important not to restrict this air flow. Naturally, your air filters must be replaced in the event of any damage. However, to maintain the maximum possible performance of your car, it is recommended to replace air filters at least every 12,000 to 15,000 miles (19,000 to 24,000 km). This interval should be reduced if you drive frequently in very dusty conditions.

It's best to check the maintenance schedule provided by your car manufacturer for the proper replacement schedule. Yes, high performance air filters from the aftermarket work. But don't expect lots of extra ponies to suddenly appear when you hit the accelerator. See the video above for more details. One of the benefits of a high-flow air filter is that, unlike regular filters, it doesn't need to be changed every year.

All you have to do is clean it approximately every two years. This is because they don't clog as quickly or as easily, but they offer better airflow and better filtration of the air entering the engine. And if your engine gets more air, then it can work better. In fact, a high-flow air filter can increase its power by approximately 3 to 5 HP and also increase its torque. At the same time, this can lead to greater fuel efficiency. How? In some of the more expensive units, the filter comes with a cold air intake unit.

It is installed to extract air from outside the car instead of the hot air used inside the engine compartment. Returning to science class, cold air is denser and therefore burns better, which improves engine performance. The aftermarket filter generated more energy, but Fenske wondered if it actually filtered less overall, too. It is very similar to a vacuum cleaner, when you notice a decrease in power; the cause may be a dirty filter because, literally, air is expelled at the cost of the vehicle's energy. A clean air filter is designed to capture dirt and debris from outside air, preventing them from reaching the combustion chamber and reducing the likelihood of you receiving a high repair bill. An air filter may not seem like an important component to check and change regularly, but it's essential for maintaining car performance. One problem that has been observed is that, due to increased air intake, high-performance filters can expose the engine to more debris and contaminants.

A particle as small as a grain of salt can pass through a damaged air filter and seriously damage internal parts of the engine, such as cylinders and pistons, which can be very expensive to repair. Whether you want to increase your horsepower, your fuel efficiency or just reduce the hassle of changing your air filter regularly, a high-flow filter can be a good option. When performing routine maintenance on your vehicle, one of the most overlooked aspects is the air filter. One is the original air filter that came with the car after thousands of miles; the second is a new OEM filter from Subaru; the third is a low-cost replacement from CarQuest; and finally there's a K&N air filter. However, there are a wide range of air filters available on the market and it's important that you get the right one for your make and model of car. Air filters are one of the easiest and fastest components to exchange for an aftermarket part; many companies claim that their design will increase power, torque and improve acceleration.
