The paper is pleated to have more surface area. Paper air filters are commonly used in modern vehicles. TYPES OF AIR FILTER MATERIALS Different air filter types are made up of different materials and used according to the driving conditions PAPER AIR FILTER To further increase the surface area, some manufacturers use inverted cone filter shape to further increase air flow. The cone shape allows air to flow at a uniform rate. Oiled air filters use cone shapes mostly. The cone shape funnels more air through it because of a larger surface area. Panel shape can be tapered further or can also come in a rounded shape. Plane air filters have a large surface area allowing more air to pass through. This shape of air filters is like a flat plane. The two main types of air filter shapes are: Shapes of air filters affect the airflow. SHAPES OF AIR FILTERS The two main shapes of car air filters are panel and coneĭifferent types of air filters come in different shapes. These air filters can be further categorised according to their shapes. These were two different types of air filters in an engine. The dirt accumulation causes damage to the engine performance and fuel economy because of the reduced airflow. Moreover, they restrict the airflow and can not be washed because of the material they are made up of.

They are more suitable for dry and dusty conditions, which means if you are going on an off-road drive in the desert, these are best suited as oil filters will need constant clean up. PROSĭry air filters require less maintenance. This is one of the types of air cleaners in cars which is generally effective for 10,000 to 15,000 miles. They restrict more airflow but ensure 99% clean air to the engine. Dry air filters are made up of paper or foam. Many Original equipment Manufacturers (OEM) design dry filters. The additional maintenance is a drawback of oiled air filters. This can only happen when you over-oil the filter while reapplying. There is a concern that oil filters damage the mass air flow (MAF) sensor. They are washable and reusable, so you don’t have to buy a new one every time your filter gets dirty. Oiled filters last more than dry air filters. The oil on the filters restrict micropollutants to flow inside, and the large micron holes allow the air to flow more easily into the engine. Oiled air filters are made up of cotton and can be cleaned easily. The upgraded intake manifolds have oiled air filters because they allow more airflow and clean around 98% of air from the dirt. Different types of air cleaners for an engine are: The car owners need to select the right type of air filters according to the driving conditions and vehicles. The primary function of an engine air filter is to clean dirt and debris from the air. DIFFERENT TYPES OF AIR FILTERS Different air filters types are used in vehicles according to the different driving conditionsĪir filters are one of the common types of car filters. Here’s all you need to know about different types of air filters in automobiles and the elements they are made up of. However, there are different types of air cleaners for cars that one should consider when replacing them. Similarly, air filters purify the air to form a proper air-fuel ratio for better functioning of the engine. It produced a 2-3 percent improvement in acceleration time versus the stock unit.Filters are very necessary for vehicles as they protect micro particles and pollutants from entering the engine and thus maintain performance. Like on the dyno, he sees incremental increases, with the K&N filter coming out on top. of torque, or around 2.6 percent and 3.7 percent, respectively).įenske also tests out the filters in a real-world environment, testing acceleration times between the four candidates. He finds that on the dyno, the aftermarket filters do in fact make more than the OEM unit, with the most gains produced by the K&N filter (around four horsepower and five lb.-ft. But not much.įenske put together a dyno test using his personal Subaru Crosstrek, comparing four different air filters: The dirty OEM item already the car, a new OEM filter, a cheaper aftermarket non-performance filter sold by CarQuest, and a high-flow performance filter made by K&N. Well, Jason Fenske of Engineering Explained put these claims to the test, and it turns out that yes, high-performance air filters do actually yield more power. But being so cheap and easy to install, it's hard to believe these filters actually produce any observable gains. If you've ever been to an auto parts store, you've probably seen air filter boxes that claim extra power and more torque over the factory filter.
