K&N 57i Generation II Induction Kits are built primarily for European vehicles. They come with K&N's Million Mile Limited Warranty™. These intake kits use only non-metallic rotationally molded tubes that can reduce air temperature and decrease intake sound over a metal tube. Restriction can exist BETWEEN an air filter and the engine reducing the benefit of a K&N Air Filter alone. The weakest link in the airflow "chain" robs a vehicle of its natural horsepower. Often that weak point is the factory air path leading to the engine. K&N Air Intake Kits virtually eliminate air path restriction by replacing the air filter and the entire air path to the engine. The aerodynamically engineered tube drives a massive amount of air into an engine, which translates into POWER. 57i Intakes are not legal for use in California and other US States adopting California emission standards.

Just installed the K&N engine air filter for my new to me BMW 325ci and wow, what a difference overall.  Wish I'd have bought K&N over the years for my other vehicles.  I'm 56, and this is my virgin K&N.  Late, I know, but I'm a fan for life now.  I just received 2 oil filters from you so that's next.  I'm a believer!!!

I purchased an FIPK for my BMW 323ci, the difference is amazing. Now I can feel the engine growl when I step down on the pedal. The kit came with everything, nothing was missing. the instructions were easy to read and it took me less than an hour to install everything. I highly recommend kn intakes. I have one in every vehicle I own. The performance is amazing, but the real perk is the gas mileage goes up. Thanks kn

I added your filter and intake tube to my BMW 325i and am more than pleased. The growl is great and it removed a low down flat spot and added a little more kick but the best bit is it improved my fuel economy by at least 1.2L per 100km, a savings of about $1.60+ per 100km. It will pay for itself in the not too distant future. I have always had a K&N filters in my cars over the years and recommend them to everyone
