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.

I installed a K &N panel filter in my Peugeot 306 HDI. The mpg has increased from 43 to 47 over a brand new paper filter. The filter will pay for itself in 5 tanks of fuel at £1.40 a litre! Fantastic product.

A very good service from this dealer. I had been meaning to replace the OEM Mann panel filter on the Peugeot 206 GTi for 9-10 months. I eventually ordered a K& N Panel Air Filter - which arrived promptly. Thank you Guy's for a great service.

Cheers,

Purchased an air filter from K&N,throttle response I feel has really increased, acceleration much improved, my Peugeot 107 although a minnow in the big pond can keep up with the best on a motorway.
