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.

I bought this filter as a gift for my girlfriend's 2013 Fiat 500 Abarth. The filter has broadened and flattened the car's power curve. It is somewhat less dramatic than the all or nothing power delivery experienced with the stock air filter. There is a definite performance improvement over a larger RPM range. Doesn't hurt that the noise from the blow-off valve is louder either!

I've installed this filter three days ago and I'm already seeing results from it. The acceleration response is faster than before, the car seems to be breathing easier now. My fiat is a 69hp automatic pop version, but it feels like I get more out of the engine than before. I'm very happy with this filter, because my country has very strict regulations regarding the modification of your own vehicle. The one thing that I'm missing, is the better sound of the car. It might be, that you have to install a different exhaust other than the stock to hear the difference. The negative thing about the filter is the smell when you first install it and start up the engine. I noticed that it somehow smelled like something burned, it might have been due to the fact that the filter is very oily at the beginning, but after a couple of kilometers/miles, the smell disappeared. I would like to recommend this product to everybody, who likes to take care of their car, improve the engine performance and reduce fuel consumption.

Installed on a Fiat 500S 1.2. Installation was all pretty straight forward, the only slight problem I had was with the following instruction: Fit the supplied rubber cap to the vacuum pipe on the inlet manifold. (Fig. 9) The inside of the rubber cap just wouldn't fit over the vacuum pipe. Plus when you compare the internal diameter of the vacuum hose (which is originally fitted onto the vacuum pipe) to the rubber cap, the rubber cap is much smaller and I just couldn't get it over. In the end I just reattached the vacuum pipe and stuck the rubber cap down the end backward and then hid the pipe! So in the end it all worked out just fine. I have quite small hands and trying to get the rubber cap over the end of the inlet manifold was difficult for me, so god knows what ham fisted people do. Anyway.... the kit makes the car sound really nice and performance has slightly improved.
