Are high-performance engine air filters worth it? The answer is yes! High-performance air filters can provide a range of benefits, from increased horsepower and torque to improved fuel economy. Not only that, but they also don't need to be changed as often as regular filters. High-performance air filters draw air from outside the engine compartment, where the air is colder. This colder air is denser and therefore burns better, leading to improved engine performance.
In fact, a high flow air filter can increase your horsepower by about 3 to 5 HP and also increase your torque. This can result in higher fuel efficiency. In some of the more expensive units, the filter comes with a cold air intake unit. This is installed to extract air from the outside of the car instead of the hot air used inside the engine compartment.
K&N high-flow filters allow for greater airflow and better filtration of the air entering the engine. This can lead to an increase in acceleration and power. However, it's important to note that these gains are usually small and you probably won't feel a huge difference when you hit the accelerator.
K&Nfilters also come with their own secret sauce - filter oil - which helps to prevent contaminants from entering the engine.
The EPA has not tested oil-bathed filters or other free-flow air filters, but it has conducted tests comparing conventional clogged air filters to new ones. The results showed that high-performance air filters do indeed produce more power. The importance of performance gain depends on the vehicle in question, but upgrading an engine's air filter is still one of the easiest and most cost-effective modifications a homeowner can make. One potential downside is that high-performance filters can expose the engine to more debris and contaminants.
In conclusion, high-performance engine air filters are worth it! They can provide a range of benefits, from increased horsepower and torque to improved fuel economy. Plus, they don't need to be changed as often as regular filters.
