K&N Filters Overview

K&N Filters Overview

K&N users would probably be surprised by the amount of air filtration testing and scientific research that goes on in K&N facilities as well as in independent laboratories. As the leader and originator of the high flow performance air filter we are always looking for new ways to provide excellent protection and maximum power for your car, truck, motorcycle, and just about anything else with an engine. In 2005 more than 1600 vehicles were tested by K&N's R&D group on dynamo meters in the US, United Kingdom, and the Netherlands. In addition to these power and torque tests, we also performed more than 110 filtration tests and more than 1,200 air flow tests with our in-house state-of-the-art test equipment.
