About this product

Part #: 57-0574

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 provides 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.

What made you choose this particular product?
Needed to replace my cabin filter. Decided to get a washable filter and save money in the long run.
Is this your first time buying from this brand? Did you consider other brands?
No. I used to have the filtercharger installed as my air filter.
Was it easy to install? Any installation tips that will help others?
Myself. There is videos on YouTube if you haven't done it before. You don't even need tools.
Once you've had a chance to use the product, did it meet your expectations?
I'll have to update you later. I just installed it 5 mins ago. But judging by construction and materials this will stay in the car for the life of the car.
Any additional comments?
I do recommend this part if your air conditioning starts off smelling anything but crisp.
