Are high-performance engine air filters worth it?

Performance filters are better suited for drivers who want performance benefits; invest in one of them if you want to increase power. While high-performance filters offer advantages in terms of power, they don't usually filter contaminants more effectively than standard, high-quality air filters. The numbers are small and you probably won't feel the extra power. One of the advantages 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 easily, but they offer better airflow and better filtration of air entering the engine. And if the engine gets more air, it can perform better. In fact, a high flow air filter can increase your power by 3 to 5 HP and also increase your 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 used hot air from inside the engine compartment. Going back to science class, cold air is denser and will therefore burn better, which will improve engine performance. Thanks to the 20,000-mile filter change schedule, Mike will have already saved money with his K&N filter after just two scheduled air filter changes. It's important to note that high-performance air filters are considered a modification and can void the warranty if you have a new vehicle that is still within the warranty period.

A high-performance air filter is more technically known as a high-flow air filter, which explains how it differs from a normal air filter. While I've never been the type of person who especially stresses getting the most out of my car's power (when I was a car owner), I've always been skeptical of the possibility that a high-performance air filter would have any significant difference from a standard one. The clean filter represented a marginal improvement compared to the dirty filter, the cheap one represented a marginal improvement compared to the clean OEM filter, although there is a risk that it was due to perhaps less material and, therefore, less real filtering and, finally, the K&N performance filter showed the best improvement, almost eight horsepower compared to the dirty filter and a 4.3 percent improvement compared to the cheaper alternative filter. In the video, Jason begins with dynamometer tests of a dirty air filter, an identical filter that is simply clean, a cheap alternative filter to the OEM, and then a high-performance K&N filter.

Assuming you drive a car for 400,000 miles, with a filter service every 20,000 miles, the cost of disposable filters can quickly increase. What Fenske doesn't check is how well each aftermarket filter actually filters the air entering the engine compared to the unit. standard. The cooler air outside the engine compartment is denser than the warm air inside the engine compartment, which is heated by internal engine combustion and other movement mechanisms that generate heat through friction.

If you've ever been to an auto parts store, you've probably seen air filter boxes that offer more power and torque than factory filters. 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. For some people, adding a high-performance air filter isn't a necessity, but something worth buying simply because they're interested in modifying their vehicle. He discovers that, on the test bench, aftermarket filters actually generate more than the OEM unit, and the K&N filter produces most of the profits (around four horsepower and five pounds).
