Description

The K&N 57S-4900 Performance Airbox replaces the restrictive factory air filter and air box. K&N performance air boxes 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-4900 Performance Airbox comes with a custom shaped K&N high-flow air filter and a fully enclosed injection molded air box that connects up to the factory air intake hose. The 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 performance air box is relatively easy to install into the previous air box space with commonly available tools. K&N builds these air box 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.

Damaged Shipments

If your shipment arrives damaged, whether visible upon delivery or discovered after opening the package, please follow these steps immediately:

Contact Gearhead Motoring as soon as possible and submit a damage claim at shipping@gearheadmotoring.com
Keep all original packaging materials, including the box and packing materials.
Make a list of any damaged or missing items.
Take clear photos of the damaged packaging and the affected products.
If the delivery driver cannot wait for an inspection, or does not allow you to inspect the shipment, write "SUBJECT TO INSPECTION" on the delivery receipt before signing and ask the driver to acknowledge it.

Once we receive the required information, Gearhead Motoring will work directly with the shipping carrier and arrange a pickup if necessary. Do not return any merchandise without prior written authorization and an RMA number from Gearhead Motoring.

After the returned product is received and inspected, we will notify you whether the item will be replaced, or if a refund or store credit will be issued.

Important: By signing and accepting a freight shipment, you may waive your right to file a damage claim for any damage not noted on the delivery receipt. We strongly recommend inspecting all freight shipments upon arrival, even if the outer packaging appears to be in good condition.
