The American-made K&N air filters are unique worldwide.
K&N uses high-quality cotton gauze (surgical gauze) with a lubricating coating between layers of wire mesh.
This special combination allows for a very high flow rate, minimal restriction, maximum filtration, and long lifespan. When it gets dirty, using the special cleaning kit, you simply wash it, lubricate it, and reinstall it.

The performance of common air filters, made of paper or sponge, drops sharply when they are slightly dirty, unlike K&N which can have maximum performance even after 80,000 km without cleaning.

As proof of their high-quality construction, K&N air filters are used by 80% of off-road motorcycle racers and Formula 1 factory teams.
