57i Series Kits > Performance Intake Kit

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.

Customer Feedback

In a word UNFRIGGIN'BELIEVEABLE Now where do I start .....Hmmmmm. Appearance: The part installed adds a very nice custom look to the vehicle with minimal expense. The parts themselves are all very well-made and clearly made out of high quality materials which will definitely last the lifetime of the vehicle. It would be nice if a second metal version of this kit was offered as well, but the plastic polymer materials look pretty bulletproof to me and the metal parts are all painted real well and will clearly last a long, long time. Add in the cool factor and this product is a home-run and is exactly what I was hoping for and what I would expect from K&N. Materials: Included absolutely everything yu would need to complete the task from instructions to every nut, bolt and clamp necessary for a 2005 BMW 325i 4-DR E46 chassis with the 2.5L V6 motor facelift hood. It is K&N guys, so the materials are top-notched as would be expected for the price and keep in mind there are plenty of other manufacturers offering more expensive intakes made with inferior materials, trust me I have checked them all before I decided on this FIPK for my car. Installation: If you are even slightly mechanically inclined it should take you much less than an hour to install from start to finish. If not, then maybe the 90 minutes K&N says. Personally it took me 21 minutes from start to finish. There are plenty of DIY videos on youtube, but honestly it is so straight forward I personally didn't even have to look at the instructions, the picture of the finished product covers it all. Performance: The car definitely has a power boost pick up with the allowance of more unrestricted air entering the air-stream. The motor sounds more aggressive for sure. This is not a turbo or an exhaust so my expectations were realistic, I was just hoping for little bit better get and go when I hit the gas pedal and this FIPK does that and more. OVERALL CONCLUSION: I consider myself the average everyday consumer, so I think most people ask themselves the same question I did after installing this product and that is very simply Is it worth spending this kind of money on a product like this. MY opinion and answer is ABSOLUTELY YES! I got a great product that was easy to install, has improved my vehicles performance and is sexy as hell. What more could you ask for. I wanted to give a decent-sized review because one word reviews like AWESOME, GREAT and WOW tell me nothing about the product. I hope this review helps to convey my PERSONAL experience and if it helps you make your decision then I have accomplished my task. Just plunk down the money and get yourself one, I GUARANTEE you won't regret your decision and YOUR CAR WILL THANK YOU AS WELL! ONE LAST NOTE: I ALSO PURCHASED THE K&N COVER FOR MY FILTER AND I HIGHLY RECOMMEND TO ANYONE GETTING ONE OF THESE THAT THEY DO THE SAME. It adds an extra $30 to the final cost, but it really does help to complete the package. Personally I think K&N SHOULD OFFER THESE PRE-FILTERS WITH THESE KITS, BUT THAT IS JUST MY PERSONAL OPINION.

I bought this filter for my brothers 328i BMW and just like every other K&N filter I've purchased, it's solid. The Germans recommend changing the oil every 10,000 miles and so this filter is perfect. After changing the oil and installing the filter, the car rides smooth. Thanks I've been a customer for a while and you will continue to have my support.

Used this for my 1994 BMW 325i Convertible show car. Great replacement over open filter that I did have, the TK-14084-2 Works and looks great, Thank you very much.
