K&N automotive OE (original equipment) replacement air filters generally add 1 to 4 horsepower to your vehicle, due to the unique characteristics of our filter media.
K&N air filter media was originally developed in the dust, sweat and tears of desert motocross racing. K&N air filters were created for an environment that
required maximum horsepower and acceleration while protecting the engine from the dirt and dust of off-road racing.
This resulted in an air filter designed to achieve high, virtually unrestricted air flow while protecting your engine for the life of your vehicle.
K&N washable and reusable air filters are made up of four to six layers of cotton gauze layered between two sheets of epoxy-coated wire mesh.
The media is pleated and oiled to enhance overall filtration and performance.
Air Filter Filtration & Engine Protection
K&N air filters offer an optimal blend of high air flow, filtration efficiency, durability and dust capacity. K&N high flow filter
media has been tested in our own in-house laboratories and by independent labs using the ISO5011 air filtration
standard developed by the Society of Automotive Engineers.
Our goal at K&N is to design air filters with the most possible airflow while providing guaranteed engine protection.
K&N Air Filter Oil
A K&N air filter is designed with four to six layers of cotton gauze media sandwiched between two aluminum wire screens.
The cotton media is then treated with a specially formulated grade of filter oil that causes tackiness throughout the cotton’s microscopic strands.
The cotton in a K&N air filter allows high volumes of airflow, and when combined with the
tackiness of the filter oil creates an efficient filtering media that ensures engine protection.
