We want to make sure that when you buy a K&N Lifetime Air Filter or Air Intake System, you can be confident your vehicle's warranty will not be impacted.  We also want you to feel confident that even if you experience a difficult dealership, we will step-in and resolve the issue, so you won't have to.  Therefore, we make the following Pledge:

K&N pledges to our customers that they will not be taken advantage of and charged for a repair due to a dealership warranty denial blamed on the presence of a K&N product. (See Details Below).

Consumers buy aftermarket products for many reasons; higher quality, added performance, visual appeal, work requirements or just as a way to be different.  The Car Companies do not like aftermarket products and never have.  They believe consumers should only buy their parts.  There is a battle going on for your freedom of choice and that freedom is being threatened by a number of wolves dressed in sheep’s clothing.  Be it in the name of emissions standards, public safety, warranty requirements, or dependence on foreign oil, all these worthy causes may be used as a reason to reduce your right to choose and force you to buy only O/E Parts.  That’s why on virtually every aftermarket company's web site; you will see a reference to the Magnuson-Moss Warranty Act, a law needed to protect your right to buy non-O/E parts.  There has even been a bill introduced recently in Congress called the “Right to Repair Act,” a bill designed to protect your right to have your vehicle serviced by an independent repair facility.

A frustrating problem we occasionally face is service technicians making false or unsubstantiated claims about aftermarket products, even something as standard as a K&N air filter going in the factory air box.  These false allegations may then used as a reason to deny a legitimate warranty claim and force a consumer to pay money when they should not.  We are horrified that the presence of aftermarket products could in rare instances be used as an excuse for taking advantage of a consumer.  In all instances we have experienced so far, the dealership’s position is mere speculation unsupported by any evidence.  However, the dealership is in the “power position” and more often than not, they will win this unfair fight with a consumer, who needs their vehicle back.  We are going to balance the scales a bit.  We will use our resources to make the consumer whole and challenge the dealership.

Pledge Details
K&N warrants that a properly installed and maintained K&N product will not cause harm to any engine component and will not result in a warranty denial.  We will promptly reimburse the consumer for the cost of the repair if a dealership denies warranty coverage as a result of a K&N product.  In order to receive reimbursement, a consumer must provide the following:

1. A written statement or repair order from the dealership in which the dealership blames the problem or warranty denial on a K&N product.

2. A written request to the dealership to send the broken part directly to K&N at K&N’s expense.  We will need the evidence.

3. Your cooperation in helping us pursue our claim for reimbursement from the dealership.

K&N will then contact the dealership and insist they present evidence to support their allegation or reimburse K&N for the cost of the repair.  We strive to exceed consumer expectations.  Customer service can be reached at 1-800-858-3333.
