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.

Customer Feedback

This filter is for a Renault delivery truck used by Winnebago as a LeSharo motor home.  It is difficult to find these parts in the U.S.  This store was very useful in finding the correct air filter for my rig.  Many thanks.

Not the first time that I use your products ( Volvo 460 & Citroen BX with carburators / K&N - 56-1651,Renault Clio 1.2 / K&N RX extreme series ), and now this one in Fiat 500L with 1.4 engine. All are great, I hope you'll make oil and fuel filters to for my Fiat. Sorry on my english, whish you all the best.

What a great kit I dont know much about car engines I wouldn't even know how to an oil change but it took me about 45min to install the 57i Induction kit in my 2002 Renault Clio. I noticed the difference in power and the great note to the engine straight away.
