The K&N 57-1002 FIPK air intake system replaces the restrictive factory air filter and air intake housing in some BMW models. K&N intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This allows your BMW’s engine to inhale a larger amount of air than the factory air filter assembly. More air means more usable power and acceleration throughout the engine’s RPM range. The 57-1002 air intake comes with a K&N high-flow air filter and a heat shield that installs into the lower air box and connects to the factory fresh air tube. Air is directed past the mass air sensor and through an aerodynamically engineered intake tube into the engine’s throttle body for a guaranteed power gain. The tube accommodates the crankcase vent tube. The oversized tapered conical air filter can be used for up to 100,000 miles before servicing is needed depending on driving conditions. This air intake is relatively easy to install usually in 90 minutes or less using the existing factory mounting points. The tools needed are a screw driver, ratchet set and several wrenches. K&N 57 Series FIPK's are street legal in all 50 US states and come with K&N's Million Mile Limited Warranty.

K&N 57-1002 Air Intake Product Reviews

Thursday, March 10, 2016 - Part 57-1002
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.

It performed alright. It gave me an extra mile out of each gallon. A slight increase in throttle response. Horsepower gains were unnoticeable (if there were any). The sound improvement was the most impressive feature. A little too expensive for what you can get out of it. Would rate higher if price was lower. Would rate lower if sound was not improved.

Instruction was good, but there was some difficult parts in the construction that would of been easier with further instruction
