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.

Fitment is great, it looks good and works as advertised. I run K@N filters in all of my vehicles because they are easy to clean and maintain. The fact that they work for a lifetime and I never need to buy another filter is an added bonus. There are power gains to be had by using these filters. Will you feel it in the seat of your pants? No, but my mileage has gone up every car I have.

Just popped this in my Dad's Alfa Romeo Brera 2.4 JTDM. The difference was very noticeable when I took it out for a test drive. The engine was much looser and responsive. Only giving 4 stars as its just been put in but I'm sure it's worthy of 5. Gave me that extra little push back into the seat : )

Put this on wife's 2014 Durango R/T with the 5.7 Hemi. It has a noticeable power increase on regular around town acceleration. You don't have to use the accelerator as much to get to your normal driving speeds. I think that is where you will receive a MPG gain, if any. The good whoosh sound noise doesn't really come in 'til you dig deeper on the accelerator and then it sounds terrific. Makes my kid laugh in the back seat every time. I wouldn't recommend buying it if you are just looking for MPG gain because it is probably not significant enough to pay for itself. I would recommend buying it for the improved throttle feel and the great sound it makes when you drop the hammer.
