K&N 57i Series Induction Kits are specifically designed for each different vehicle and will free your car from the size restriction that comes with the factory air box. These economical kits can take a variety of different forms based on vehicle characteristics and available space under the hood. Each kit is designed to provide power throughout the RPM range. The extra surface area of these open-air air filters provide even more airflow at lower restriction than a K&N O/E replacement filter which is always limited to the size of the factory air box. The larger air filter also captures and holds more dirt increasing its service life before a cleaning is required (up to 100,000 miles). The filter is either directly attached to the engine carburetor or throttle body or indirectly through a tube assembly running from the filter to the engine. All adapters are made from high quality materials such as steel, aluminum, silicon or reinforced nylon to ensure long life. 57i Intakes are not legal for use in California and other US States adopting California emission standards.

Customer Feedback

I couldn't get it shipped to me in NY, but I ended up getting one. I have to be honest it took about 30 mins to install and wow what a difference I own a 09 Audi A4 2.0 turbo Quattro. I also had my car ECU done by APR stage one and between the air charger and the ECU upgrade wow this car is like a rocket now. I love the noise it makes sucking in air out of the air charger.

I have tried K&N Air Filter (E-2999) in my 2013 Audi A8 3.0L fuel type and I have really noticed the difference in terms of performance, initial torque and even horsepower. When you start accelerating, you can hear the air flowing through K&N filter and it really sounds good. Moreover, I can estimate the increase in hp to be around 30 hp which is great by only replacing the original air filter to K&N. Note: make sure to ask you car service provider if you are allowed to use them or not in order to not lose the car warranty. In my case, I usually remove them before the sending my car for routine checks.
