Frequently Asked Questions

Not at all. Most disposable filters are "barrier filters”, which act as a physical barrier to dust particles. Once a dust particle covers a pore in the media, air can no longer flow through that space. K&N replacement air filters absorb dirt and dust particles instead of physically blocking them, allowing the pores in the material to continue to let airflow through.

Yes, K&N replacement air filters are emissions legal in the United States.

K&N replacement air filters that fit into the factory air box can go up to 50,000 miles before cleaning is required, and large conical filters on a K&N air intake system can go up to 100,000 miles before needing to be cleaned, depending on your driving conditions.

We do not recommend using other detergents or solvents to clean your air filter, or other types of oil. Products other than those manufactured by K&N have not been tested and may deteriorate the performance and filtering ability of your air filter.

If one of these products ever fails to provide complete satisfaction, K&N will replace it.

What Is Not Covered By Our Warranty

Any K&N product used for 1: any type of racing or competition; 2: any off-road use, custom or modified applications; 3: any off-road or dual sport motorcycle/ ATV use; or 4: any illegal highway use, marine, or industrial applications. All K&N Air Filters not covered by our million mile warranty are warranted against defective materials or workmanship for one year from date of purchase with no mileage limitation.

Incorrect Cleaning or Use Voids Warranty

Engine Protection Limited Warranty

Unlike many companies, our warranty for O/E replacement air filters and intake systems does extend beyond the replacement of a defective K&N part. For the original purchaser of the product, our warranty covers any engine damage or related costs incurred as a direct result of the use of a properly installed and maintained K&N O/E automotive replacement air filter or intake system on the specific vehicle for which the product was designed to be used by K&N. This includes reasonable vehicle repair costs directly related to an engine problem caused by the failure of a K&N product. Furthermore, we warrant that using our product will not result in a vehicle warranty denial. K&N will not be responsible for any indirect, consequential, special, contingent, or other damages not listed above.

We will promptly reimburse the consumer for the cost of the repair if a service provider denies warranty coverage as a result of a K&N product or claims that a K&N product has caused harm to your engine or vehicle. In order to receive reimbursement, we require each of the following:

  1. The consumer must provide a written statement or repair order from the dealership or service provider in which the dealership or service provider blames the problem or warranty denial on a K&N product.
  2. The service provider or consumer must provide K&N with all allegedly damaged parts. Many states have laws that require a service provider to retain all parts replaced during a vehicle repair, unless given consent to dispose of the parts by the consumer. K&N will pay the shipping cost to recover these parts.
  3. The consumer must provide proof of purchase of the K&N product along with cooperation in helping us investigate the claim.

Once these steps have been completed, K&N will contact the service provider and collect evidence to support their claim. In the event we are not provided with sufficient evidence, we reserve the right to reject the claim and will use our best efforts to assist in establishing your rights toward the service provider under warranty or other provisions.

We strive to exceed consumer expectations. Customer service can be reached at 1-800-858-3333.
