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 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.

Be the first to review part 57-0126-1
I have a Land Rover discovery 2004 and have always suffered with it hanging back until the rev counter reached the 1500 mark. I was advised to install a K&N air filter, and what a difference. The whole performance across the range showing improvement.

Having been motoring for over 40 years, I have always fitted K&N filters on big Japanese bikes and various cars. Apart from their obvious air flow benefits, pair that with the build quality, they will last for years. With a wash and reoil with K&N products, they will out last anything on the market. At present, I run them in my wives Rover and my sports x type Jag and I would recommend them to anyone.

I am very familiar with the fine products and performance value K&N delivers. I've used these incredible filters on all of my vehicles (two Jeep, SRT, 8 SUVs and my current 2014 Range Rover Sport 5.0L Supercharged) I can feel the difference.
