Air Intake System
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. 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.
