The K&N 57S-9501 Performance Airbox is an air intake system that replaces the restrictive factory air filter and air intake assembly. K&N intakes are designed to dramatically reduce air flow restriction as well as smooth and straighten air flow. This allows your engine to inhale a larger amount of air than the factory air filter assembly. More air means more usable power and acceleration throughout the engine’s RPM range. The 57S-9501 air intake comes with an oversized cone shaped K&N high-flow air filter, a fully enclosed injection-molded air box, a mandrel-bent aluminum air intake tube and a flexible air intake hose. The aluminum air intake tube is powder coated in a durable textured black finish. The performance air box has a removable lid for easy access to the filter when cleaning is required. The air filter can be used for up to 100,000 miles before servicing is needed depending on driving conditions. This air intake system is relatively easy to install usually in 90 minutes or less using the vehicle’s existing factory mounting points with commonly available tools. K&N builds these air intake systems to last for the life of your vehicle and they are backed by K&N's Million Mile Limited Warranty. Some K&N 57S Series Performance Airboxes are compliant with the latest TUV emissions and sound regulations. Check the K&N catalog or website for vehicle applications and specific TUV status for each vehicle and air intake.

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 dynamometers 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.
