Do k&n air filters really improve performance?

Fenske also tests filters in a real environment, testing acceleration times between the four candidates. Just like on the test bench, you see incremental increases, with the K%26N filter coming out at the top. Produced a 2-3 percent improvement in acceleration time compared to the standard unit. Yes, aftermarket air filters work.

But, don't expect a bunch of extra ponies to suddenly appear when you hit the accelerator. See the video above for more information. Those are some pretty small gains, but do they show up in real world driving? The differences between clean and dirty OEM filters were negligible, but the cheap aftermarket filter improved acceleration times by approximately 1.2 percent. Filter K%26N fared better, as acceleration times improved by an average of 2.74 percent.

More air equals more power, and oversized K%26N high-flow filters will allow for greater airflow. While replacing only the OEM air filter with a K%26N high flow filter will add power and increase acceleration, the biggest gains will come from installing a complete cold air intake system. You'll get improved throttle response, slightly better mpg, and maybe a few horsepower, if you use a drop down panel filter. You'll get a little more from a cone filter with a thermal protection tube %26.A cold air intake, if available, will make the most of.

Of course, as you climb the ladder of admission types, the price increases accordingly. Therefore, running without the filter allows dirt to contaminate and damage the sensor, which can lead to incorrect airflow readings, which, as you know, is vital for fuel ratio calculations. The trademarked red filter (usually conical in shape) on display or your kit may include an airbox closed. Fitting a K%26N high flow air filter is the easiest, most cost-effective and least technical way to increase engine performance.

A filter provides protection against water ingestion, a common cause of hydraulic blockage that often ends with a destroyed engine. An air cleaner has a conflicting requirement that is not to prevent airflow to the engine (if technically possible, allow an “unrestricted” flow of clean air to the engine). Finally, the K%26N filter was installed, which allowed the engine to produce 164.42 hp and 142.53 lb-ft of torque. A factory air intake typically feeds hot air to the cylinders, while K%26N high-performance air intake systems are designed to provide a smooth, unobstructed path for the air stream, keeping the air stream fresher and denser in oxygen.

This allows a K%26N air filter to capture contaminant particles that are much smaller than the openings within the filter medium. Personally, I use K%26N air filters because I live in a dusty area and I usually spend more on paper filters than on oil filters. It really is that simple and that's why upgrading an engine's air filter is the easiest and most cost-effective modification a homeowner can make. In addition, if the filter becomes clogged with particles for a period of time, less air (and therefore oxygen) is supplied to the engine.

The K%26N filter can add a little noise here and some ponies beyond (not much), but it's reusable, so I have one myself. Due to high levels of pollution, air filters tend to choke with particles and it is recommended to clean or replace an air filter in every general service of your car. Without further ado, the dirty OEM air filter allowed the car to produce 158.25 hp and 137.25 lb-ft of torque. .
