Are More Expensive Car Air Filters Worth It?

The high-performance air filter is not only capable of providing a slight increase in horsepower, but it can also improve the fuel economy of your vehicle. This is because these filters draw air from outside the engine compartment, where the air is colder. According to Stack Exchange, a network of 180 Q26A communities including Stack Overflow, the largest and most trusted online community for developers to learn, share their knowledge and develop their careers, you can expect to get about 1BHP more from a good quality filter.


, unless you have a very sensitive ear, you won't be able to notice the difference.

What better quality filters do have is that they take longer to clog. This means that they don't actually give you more power, but rather they are better at avoiding energy loss once you've driven a couple of thousand miles. It all depends on the application. I personally paid good money for a K&N air filter for my old traveler, an 18-year-old Subaru 4-cylinder.

After installation, I heard a pretty clean grunt noise from the engine when accelerating, but the idle and mileage and gasoline performance were the same. On the other hand, when I installed a K&N air filter on my Kawasaki Concours, I noticed not only a cold grunt noise when accelerating, but also a smoother idle and a small increase in top speed performance above 7,000 rpm. So there you go, I think they're worth the money and time spent cleaning them every few thousand miles if used in a performance application, but for a normal old car, the standard, cheap paper filter is the way to go. Once you have decided to change the air filter, the first question that will come to mind is whether you should go for an affordable or expensive one. It all depends on your financial situation and how much personal care you give your vehicle.

Both types of filters will remove dirt and offer clean air to your engine, but any brand air filter will last longer than an inexpensive non-brand one. One of the benefits of a high flow air filter is that unlike normal 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 perform better.

In fact, a high flow air filter can increase your horsepower by about 3 to 5 HP and also increase your torque. At the same time, this can lead to higher 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 of the car instead of using hot air from inside the engine compartment. As we all know from science class, cold air is denser and therefore will burn better, thus improving your engine performance. An air cleaner is an essential part of any motor vehicle's fuel supply system as it plays a vital role in keeping the engine clean and free of dirt.

For harder to find sizes for older vehicles, Green Filter also offers larger diameters with its factory replacement air filter. I tested a new market-leading oiled air filter against a Ford factory standard paper filter. So if you have a custom car or a vehicle with an engine change that uses this harder to find style air filter element, search those categories first or try searching for it using the check boxes in the names of filter manufacturers. The air filter helps remove insects, dirt and other things from indoor air while keeping those debris out of your vehicle's engine. Universal fit air filters can specify outer diameter, inner diameter and height measurements if they are round. After removing the vehicle filter, first spray cleaning solution thoroughly on all sides of the filter including interior area of conical air filters.

Second, high airflow and high particulate removal are at odds according to filter technology. When performing routine maintenance on your vehicle one of the most overlooked aspects is the air filter. Any expensive and durable air filter will not only increase the life of your engine but will also protect you from costly engine repairs. Expensive high-quality air filters not only deliver clean air to your engine but also remove mold spores dust allergens and other pollutants that everyone in car inhales. Cotton filters usually come with kit that includes bottle of cleaning solution and another bottle of oil to spray filter by hand when it dries after washing. Most automakers don't use cone-shaped filters as standard equipment but for those that do these can also serve as OEM-style replacement filter elements which also improves performance. You can also change your air filter every year when you change your engine oil or when you feel there is an abnormal decrease in mileage offered by your vehicle. Beyond simple upfront costs technology behind aftermarket filters saves them even more money while driving compared to original equipment paper filters.
