Genuine Parts
The K&N Performance Airbox is designed to dramatically reduce air flow restriction as well as smooth and straighten air flow. Replacing the restrictive factory air filter and air box allows your engine to inhale more air than with the factory air filter assembly. More air means more usable power and acceleration throughout the engine's RPM range. A fully enclosed injection molded air box connects to the factory air intake hose. The removable lid provides easy access to the filter when cleaning is required. This performance air box is relatively easy to install. The required tools are commonly available and it uses the previous air box space. These air box systems are built to last for the life of your vehicle and they're 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.

New product returns are subject to a 15% to 25% restocking fee and loss of outbound shipping. It is the responsibility of the buyer to ship back returns. Items returned need to have your original order number on the box next to the shipping label. NP Motorsports is not responsible and cannot accept returns that are damaged during return shipping.

NP Motorsports is not responsible for theft of a delivered package. Please act accordingly when selecting a shipping location.

If packaging of any returned item is not the same as how it was shipped out, NP Motorsports is not responsible for any additional damage occurred during return shipping.

Returns are handled on a case by case basis:

  •  The Product Arrived Damaged - NP Motorsports will pay to ship the product back to our facility and ship you an undamaged product. Damaged products must be reported within 3 days of receiving the item. NP Motorsports  requires pictures of damaged product to verify damage. Once damaged product has been verified, NP Motorsports will send a return label for product to be shipped back. 
  •  The Incorrect Product was Ordered - A 15% to 25% restocking fee is applied plus the customer is responsible for shipping the product back to us. The product must be unused with no signs of wear. We will be happy to assist you in ordering the correct product. 
  •  The Correct Product was Ordered, the customer changed their mind: A 15% to 25% restocking fee is applied plus the customer is responsible for shipping the product back to NP Motorsports. The Return address is different from shipping address, so the customer must reach out to NP Motorsports before shipping any part back. The product must be unused with no signs of wear, scratches, or debris.
