Having the best air filters can make a huge difference in the life and the performance of an engine. It is an essential component of the air intake system and is tasked with trapping any dirt or debris in the air from entering the intake. It is important that these tiny pieces of dirt, road salt, pollen, or other contaminants not be allowed to enter the engine. As it can damage pistons, clog valves, and generally shorten the life of your engine or even kill your power plant. An air filter is made of paper, cotton, or gauze. This material must trap dirt and still allow air to pass through. When too much dirt builds up in the air filter, the air flow into the engine will suffer and it will need to be replaced. Not changing the air filter can reduce the engine's performance and decrease the MPG of the vehicle. You can replace your air filter with a direct paper replacement or you can upgrade to a performance air filter, K&N Air Filters.

K&N Air Filters are some of the best performance air filters on the market today. The filter's media is made of cotton and gauze, and sandwiched by aluminum wire screens. They allow for more air flow while still providing excellent filtration. Increasing the flow of air into your engine will increase horsepower and acceleration since your engine will be operating more efficiently.

K&N Air Filters are washable and reusable. They are easily cleaned and oiled using a K&N Recharger Kit. They can be cleaned and oiled as many times as reasonably necessary. In a laboratory tested by K&N Air Filters, K&N air filters have been washed and re-oiled more than 100 times and still performed up to specification. Depending on driving conditions, they usually can go up to 50,000 miles before they need cleaning. Stock paper air filters need to be replaced about every 8,000 miles. Consider the money you can save over the course of 100,000 miles. The environment will thank you for using a reusable air filter as you can prevent used paper air filters from piling up in land fills. K&N Air Filters come with a Million Mile Limited Warranty so they are sure to last the life of your vehicle.

K&N Filters WILL NOT void your vehicle’s manufacturer warranty.

Under the Magnuson-Moss Warranty Act, Title 1, ..101-112, 15 U.S.C. ..2301 et seq., effective July 4, 1975, prohibits a vehicle manufacturer to void the vehicle warranty just because aftermarket air filters are on the vehicle. There are two types of new car warranties and the two types of emission warranties.

When a vehicle is purchased new and the owner is protected against the faults that may occur by an expressed warranty - an offer by the manufacturer to assume the responsibility for problems with predetermined parts during a stated period of time. Beyond the expressed warranty, the vehicle manufacturer is often held responsible for further implied warranties. These state that a manufactured product should meet certain standards. However, in both cases, the mere presence of aftermarket parts doesn't void the warranty.

There are also two emission warranties (defect and performance) required under the Clean Air Act. The defect warranty requires the manufacturer to produce a vehicle which, at the time of sale, is free of defects that would cause it to not meet the required emission levels for it's useful life as defined in the law. The performance warranty implies a vehicle must maintain certain levels of emission performance over it's useful life. If the vehicle fails to meet the performance warranty requirements, the manufacturer must make repairs at no cost to the owner, even if an aftermarket part is directly responsible for a warranty claim, the vehicle manufacturer cannot void the performance warranty. This protection is the result of a parts self - certification program developed by the Environmental Protection Agency (EPA) and the Specialty Equipment Market Association (SEMA).

If a dealer denies a warranty claim involving an implied or expressed new car warranty and you would like help, you can contact the Federal Trade Commission (FTC). The FTC works for the consumer to prevent fraudulent, deceptive and unfair business practices in the marketplace and to provide information to help consumers spot, stop and avoid them. To file a complaint, you can call toll-free, 1-877-FTC-HELP (1-877-382-4357), or use the online complaint form. The FTC enters Internet, telemarketing, and other fraud-related complaints into Consumer Sentinel, a secure, online database available to hundreds of civil and criminal law enforcement agencies worldwide.
