K&N air filters work in both real life and tests. They offer an easy and effective way to gain an improvement and are a basis for more performance.
The air filter cleans air the engine needs to burn fuel, but there are different filters on the market - some flow and clean better and some worse.
K&N filters both clean and flow much better than an original paper filter or cheap imitations.
To select a filter, please select your car make and model from the dropdowns. The images of each air filter are of the actual product to offer extra certainty and help in cases where one car has more than one filter used on it.
More power and less consumption?
The engine is basically a large air pump. It sucks air through the filter, and when a filter flows better, less power and fuel is used to suck air through the filter, and in turn can be used as horsepower to accelerate.
The most popular upgrade to any car
Because an air filter is so easy to change and offers great benefits, it is a popular - perhaps the standard - of upgrading the performance of your car. Keepin the air filter clean is important, and we suggest you also get a K&N recharge air filter cleaning and oil kit. A good interval for cleaning the K&N air filter is twice a year.
