The most obvious benefit of changing your air filter is the increased fuel efficiency you'll see after you change it. Since it improves airflow to the engine, your car doesn't have to work as hard, so it burns less gasoline. Increasing airflow to the engine can help improve the overall performance of your vehicle. Replacing a clogged air filter can increase fuel efficiency and improve acceleration, depending on the make and model of your car.
When you realize that, it makes sense to replace your air filters regularly. Fuel economy has been improved because high-performance air filters draw air from outside the engine compartment, where the air is colder. That is, it has the ability to remove the filter and clean it with liquors and reinstall it in the housing, which saves the cost of buying a new filter and at the same time keeping the old filter out of the landfill: win, win. A particle as small as a grain of salt can pass through a damaged air filter and cause a lot of damage to internal engine parts, such as cylinders and pistons, which can be very costly to repair.
However, there is a wide range of air filters available on the market and it's important that you get the right one for the make and model of your car. If you drive with a lot of traffic on a regular basis, the air filter won't last that long. You're going to have a lot of stop-and-start driving, which places more demands on your car and will also make your air filter dirty faster. Air filter replacement can be part of a general tuning service that will help you get better mileage and performance out of your vehicle.
A good indication that the air filter needs to be replaced is the presence of black smoke coming from the exhaust pipes when you start the engine. The cooler air outside the engine compartment is denser than the warm air inside the engine compartment, which is heated by the internal combustion of the engine and other movement mechanisms that generate heat through friction. After doing a cursory search online, I have found a number of websites that promise more horsepower and better mileage just by changing my air filter. The aftermarket filter generated more power, but Fenske wondered if it actually filters less overall as well.
A high-performance air filter is more technically known as a high-flow air filter, which explains well what differentiates it from an average air filter. The high-performance air filter will not only slightly increase your horsepower, but it will also improve the fuel economy of your vehicle. If you know where your air filter is located (you can refer to your owner's manual for where to look), you can do a visual inspection. While the original new and dirty filters were almost identical in their sprints (9.01 seconds from 20 to 60 mph and 3.61 seconds from 45 to 60 mph), aftermarket air filters improved that performance.
