Do you want to get the most out of your car's engine? A high flow air filter can help you do just that. It can increase your horsepower by 3 to 5 HP and also boost your torque, leading to higher fuel efficiency. While the numbers may be small, you can still feel the extra power. But don't expect a huge difference when you hit the accelerator.
Cotton gauze filters are made up of four or six layers of pleated cotton filter media, which act as a physical barrier to dirt and debris. Tests have shown that aftermarket air filters can improve performance. Cotton gauze air filters are also washable and reusable, so you don't have to replace them every time. Foam filters are used in high-performance vehicles because they do an excellent job of trapping dirt and other contaminants.
Paper air filters are simple and effective, but lack efficiency. Performance cotton air filters are the most efficient and allow maximum air to circulate in the engine. Studies suggest that, due to more efficient intake systems and air cleaner housings in today's cars, high-performance air filters may not make a huge difference in engine performance. Washable air filters last the life of the vehicle and help reduce waste.
Tests on the test bench show that aftermarket filters produce more than the OEM unit, with the largest gains produced by the K&N filter (around four horsepower and five pounds). However, it is not clear how well each aftermarket filter actually filters the air entering the engine compared to the original unit. In conclusion, a high-performance air filter can make a difference in your car's performance. It can increase your horsepower and torque, leading to higher fuel efficiency. While it may not make a huge difference, it is still worth considering if you want to get the most out of your car's engine.
