About the K&N Air Filter

The World's Best Air Filter

Filters developed for motorcycle racing in the desert

For over 30 years, K&N has specialized in improving air flow to your vehicle's engine. Originally, they developed "the world's best air filter" to cope with the extreme demands of desert motocross racing, so you can be sure it'll stand up to whatever punishment you throw its way. And the K&N Air Filter performs at a level that ordinary disposable filters can't touch.

A 21st Century air filter

K&N conducted extensive research to find the right material for their filters. The secret? Several sheets of high-flow cotton gauze are sandwiched between two layers of aluminum wire mesh, then pleated and oiled to create a filter that offers increased air flow and excellent filtration. The K&N Air Filter is washable and reusable, so your engine will be protected as long as you own your vehicle. And the K&N filter will NOT void your new vehicle's warranty.

Clean it, don't toss it

In typical driving conditions, you'll have to clean your filter every 50,000 miles.You'll need K&N's Recharger Filter Care Service Kit (not included) which contains an 8-ounce bottle of oil and a 12-ounce bottle of filter cleaner. To clean, you soak the filter in the filter cleaner, clean with water, let dry, and then recharge the filter with the K&N oil, a special blend of mineral oils and polymers.

Performance: The K&N High-Flow air filter is designed to give you up to 50% better airflow to your vehicle's engine than ordinary air filters. More air entering the engine can increase combustion efficiency, resulting in more horsepower and better acceleration.

Filtration: The filter has thousands of microscopic threads absorbing a specially formulated oil to create a powerful filtering medium that protects your engine from harmful contaminants.

Reusable: This K&N air filter is washable and reusable. Depending upon driving conditions, the filter can last up to 50,000 miles before cleaning is required. It is recommended that you clean and re-oil your filter every 50,000 miles, using the K&N Recharger Filter Care Service Kit (item # 513995050).

Million Mile Warranty: The filter is warranted for one million miles, or 10 years from the date of purchase, whichever comes first.
