MILLION MILE LIMITED WARRANTY
K & N O/E Replacement Air Filters and Air Intake Systems purchased from Authorized Dealers are backed by a Million Mile Limited Warranty when used primarily on paved roads and on vehicles for which they were designed. If one of these products ever fails to provide complete satisfaction, K&N will replace it.
WHAT IS NOT COVERED BY K&N 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. This includes K&N Air Filters sold for ATV's and off-highway or dual-purpose motorcycles.
INCORRECT CLEANING OR USE VOIDS WARRANTY
KnN Aftermarket Air Filters should be cleaned every 50,000 miles for normal highway use, more often in dusty conditions. Cleaning should be done with K&N cleaner and air filter oil (or comparable air filter cleaner and oil). Use of compressed air, or chemicals not specifically designed to clean and re-oil cotton air filters (i.e. gasoline, transmission fluid, motor oil, lightweight oil, or diesel fuel) will void the warranty. Any damaged, abused or modified K&N Air Filters will not be warranted.
Any K&N product returned to K&N will need a Return Goods Authorization number and must be sent at customers' expense along with proof of purchase.
EXTENT OF WARRANTY
Any defective K&N Air Filter properly returned to K&N will be replaced. K&N reserves the right to determine whether the terms of the warranty, set out above, have been properly complied with. In the event that the terms are not complied with, K&N shall be under no obligation to honor this warranty. K&N will not be responsible for any indirect, consequential, special, contingent, or other damages.
CONSUMER PROTECTION PLEDGE
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 difficulties with a dealership repair department, we will step-in and resolve the issue, so you won't have to. Therefore, K & N makes the following Pledge:
K&N pledges to their customers that they will not be taken advantage of and charged for a repair due to a manufacturer warranty denial blamed on the presence of a K&N product.

ENGINE PROTECTION LIMITED WARRANTY
Unlike many companies, K&N warranty for O/E replacement air filters and intake systems does extend beyond the replacement of a defective KnN 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 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, sensor replacements, car rental fees or other incidental expenses directly related to an engine problem caused by the failure of a K&N product. Furthermore, we warrant that using KN 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:
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;
The service provider or consumer must provide KN 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; and
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.

K&N Air Intake Horsepower Guarantee
K&N Intake Kits are Guaranteed to Increase Power!
MILLION MILE LIMITED WARRANTY
Every Intake Kit we design has been tested on a Dynamometer and proven to increase horsepower. We measure horsepower at the wheels. The horsepower rating that may have been on the window sticker when your car was new is often a measurement of horsepower at the engine and there can be a loss of horsepower through the drive train by the time it reaches the wheels.
K&N hereby warrants and guaranties to the original retail purchaser of any K&N air intake kit that the vehicle on which the air intake system is installed will gain an increase in horsepower, or K&N will refund the purchase price, including sales tax, to the retail purchaser, subject to the following terms and conditions:
The K&N air intake system must have been properly installed on the vehicle in accordance with the included K&N instructions.
The system must be the correct part number for the vehicle upon which it was installed.
The vehicle must be in good running condition.
The vehicle must undergo a dynamometer test both before and after the installation of the system, with no changes to the vehicle, except for the installation of the kit. The dyno tests must be performed by the same testing facility and must be performed within 30 days of one another and within 60 days of the date of purchase. The test results or work order for each test must reflect the name and address of the vehicle owner or operator having the test performed; the year, make, model and mileage of the vehicle being tested; and the horsepower results from both tests.
If the dyno tests show that the vehicle did not gain an increase in horsepower, then the retail purchaser must return the complete air intake system to K&N in its original packaging, together with his or her proof of purchase, the ORIGINALS of the two dyno tests statement requesting a refund in accordance with our Horsepower Guarantee. Upon receipt of all of the foregoing, K&N will refund the full purchase price, including sales tax, to the original retail purchaser.
This guaranty does not apply to any other costs incurred by the purchase, including, but not limited to, the dyno tests, parts and labor for the installation and removal of the air intake system, shipping costs, rental car, loss of use or incidental damages, if any, and K&N expressly disclaims any and all liability for same.
Common Misdiagnosis in Warranty Repair
There are many reasons why a dealership or repair facility may deny warranty coverage on a repair. Sometimes, people make mistakes, and technicians are no different than anyone else. A less common reason is the few "bad apples" out there who try to charge a consumer for a legitimate warranty repair, so they can make a greater profit. You don't have to be a master mechanic to challenge a repair diagnosis, just an educated consumer. Here are some preliminary resources that might be helpful.
Problems related to the use of an "aftermarket oiled air filter"
Maybe you've seen this phrase on your repair order. The dealership or repair shop says that certain engine parts or sensors need to be replaced because you have been using a K&N air filter. The truth is that oil does not come off our air filters, even under extreme conditions. The amount of oil applied to our air filters is small (usually less than 2 ounces) and once that oil is applied and evenly absorbed it will not come off until the filter is cleaned. We conducted a test with an over-oiled K&N air filter in which we flowed 1,000 cubic feet of air per minute through the filter for over twelve hours. The use of an absolute filter downstream revealed that no oil came off the K&N air filter, even in these extreme conditions. Many companies, both aftermarket and OE, use oil in their air filters, both disposable (paper) and reusable (cotton). We all use oil for the same reason: it enhances the filtration efficiency of an air filter.
Mass Airflow Sensors
The dealership or repair shop says that your vehicle's mass airflow sensor needs to be replaced, and is blaming it on the K&N air filter you installed. What steps did the technician take to arrive at that conclusion? We have never encountered a dealership or repair facility that owned the equipment necessary to test whether or not a sensor was functioning properly or to measure its output. Certain vehicle manufacturers have issued bulletins on how to test a mass airflow sensor by installing it into a "similar vehicle", but in our experience those instructions are rarely followed. There are two common types of mass airflow sensor failure: failure from silicone contamination of the sensing element, and complete electronic failure. Both of these types of failures can only be verified through microscopic, forensic/chemical, and airflow/sensor output analysis.
The dealership or repair shop says that your K&N filter let too much dirt pass through, causing premature engine wear and "dusting" of your turbocharger or engine. Dust ingestion can be hard to verify without doing a complete teardown of the engine and performing a filtration efficiency test on the air filter. Performing an oil analysis on the engine oil used at the time of failure can uncover a dust ingestion problem. If a dust ingestion problem is found, it is most likely caused by an opening or defect in the air box or air inlet duct, a fuel filter that needs replacement, or engine oil beyond its service life. It is unlikely that an air filter is the cause.
Dear K&N Consumer:
K & N Engineering, Inc., is informed that some automobile dealers and manufacturers are telling their customers that the factory warranty on their motor vehicles is "void," if an original equipment (OE) replacement air filter, manufactured by K&N, has been installed on their vehicles. K&N finds such instances disturbing, and while it does not purport to give legal advice, K&N would like to refer you to the federal Consumer Product Warranties law, often referred to as the Magnuson-Moss Warranty Act, which states, in part, in Title 15, United States Code, Section 2302, subdivision (c), as follows:
"No warrantor of a consumer product may condition his written or implied warranty of such product on the consumer's using, in connection with such product, any article or service (other than article or service provided without charge under the terms of the warranty) which is identified by brand, trade, or corporate name; except that the prohibition of this subsection may be waived by the [Federal Trade] Commission if –
(1) the warrantor satisfies the Commission that the warranted product will function properly only if the article or service so identified is used in connection with the warranted product, and
(2) the Commission finds that such a waiver is in the public interest. The Commission shall identify in the Federal Register, and permit public comment on, all applications for waiver of the prohibition of this subsection, and shall publish in the Federal Register its disposition of any such application, including the reasons therefor."
Under this federal statute, a manufacturer, who issues a warranty on your motor vehicle, is prohibited from requiring you to use a particular brand of air filter, oil filter, or other service or maintenance item, unless such item is provided, free of charge, under your warranty or unless the Federal Trade Commission (FTC) waives this prohibition against the manufacturer. KnN is unaware of any exemption or waiver granted by the FTC to any motor vehicle manufacturer, which pertains to air filters or oil filters.
K&N interprets this law to also prohibit the motor vehicle manufacturer from restricting your use of a particular brand of air filter, oil filter, etc. K&N's interpretation of this law is consistent with the interpretation given it by the FTC, the government agency responsible for the interpretation and enforcement of this federal law.
The rules and regulations adopted by the FTC, to govern the interpretation and enforcement of the Magnuson-Moss Warranty Act, are set forth in the Code of Federal Regulations, Title 16 - Commercial Practices, Chapter I - Federal Trade Commission, Subchapter G - Rules, Regulations, Statements and Interpretations Under the Magnuson-Moss Warranty Act, Part 700 - Interpretations Under the Magnuson-Moss Warranty Act. Contained within these rules and regulations is Section 700.10, which states, in relevant part (with specific language highlighted by K&N), as follows:"(c) No warrantor may condition the continued validity of a warranty on the use of only authorized repair service and/or authorized replacement parts for non-warranty service and maintenance. For example, provisions such as, "This warranty is void if service is performed by anyone other than an authorized 'ABC' dealer and all replacement parts must be genuine 'ABC' parts," and the like, are prohibited where the service or parts are not covered by the warranty. These provisions violate the Act in two ways. First, they violate the section 102(c) ban against tying arrangements. Second, such provisions are deceptive under section 110 of the Act, because a warrantor cannot, as a matter of law, avoid liability under a written warranty where a defect is unrelated to the use by a consumer of "unauthorized" articles or service. This does not preclude a warrantor from expressly excluding liability for defects or damage caused by such "unauthorized" articles or service; nor does it preclude the warrantor from denying liability where the warrantor can demonstrate that the defect or damage was so caused."
We think this FTC rule is pretty clear and unambiguous. Please note that the FTC requires the "warrantor" (this would, generally, be your motor vehicle manufacturer) to "demonstrate" that the defect in or damage to your vehicle was caused by your installation or use of a K&N air or oil filter, or other "unauthorized" part, before a warranty claim can be denied. We contend that this requires credible proof as to the cause of a failure and not merely your dealer's guess, speculation or unfounded opinion as to the cause.
Therefore, K&N considers any threat to void your factory warranty, or the actual voiding of your factory warranty, solely for the installation of a K&N replacement air filter or oil filter, to be a violation of federal law.
The foregoing addresses only your rights and protection under federal law. Of course, you may have greater rights under the consumer warranty laws applicable in your state.
If you have encountered a motor vehicle dealer, who has failed and refused to "demonstrate" or prove, as federal law requires, that your K&N air filter necessitated a repair for which warranty coverage has been denied, or a manufacturer, who refuses to perform warranty repairs on your vehicle, merely because you have installed a K & N replacement air filter or based on inaccurate information from your dealer, then we ask that you request that the dealer or manufacturer set forth, in writing, the warranty denial, together with a written statement as to the specific reasons for the denial of warranty repairs, and that you send a copy of this written statement to K&N. We also ask that you direct your dealer and manufacturer to the federal law quoted above. K&N assists consumers in this situation through the K&N Consumer Protection Pledge.
Please keep in mind that a motor vehicle dealer is, generally, not the "warrantor" of your vehicle. Your dealer may be assisting you as much as possible in getting the manufacturer to cover repairs of your vehicle under warranty, but the factory may still refuse to cover the repairs. If this happens, then there may be nothing further that the dealership can do, and it should not be blamed for the actions of your vehicle's warrantor. A dealership's control over the approval of a warranty repair is usually limited to properly diagnosing and reporting the cause of the repair. K&N only takes issue with those dealerships who advise consumers that the mere installation of a K and N air filter on a vehicle "voids" the factory warranty, or they convey to the manufacturer an unsubstantiated opinion or conclusion that a K&N air filter caused an engine or component failure, without any objective proof to support such a statement, which results in the denial of a legitimate warranty repair.
