K&N Air Filters

The last word in air filters isn’t actually a word, it’s two letters: K&N. Ask anyone who’s replaced their stock air filter and they’ll tell you. It’s the best air filter on the market.

Why the cult following for K&N? Better performance! They’re designed to increase horsepower and acceleration by providing up to 50% more air flow, which results in brisker throttle response and more torque. While K&N declines to comment on whether their air filters help increase gas mileage, there are plenty of user reviews online raving about an increase in mpg after installing a K&N filter.

K&N Air Filters Features and Benefits

Reusable and Lasts Up to 50,000 Miles Between Servicing

K&N makes an easy-to-use air filter cleaning kit you can use to clean and re-oil your filter. Clean it every 50,000 miles and you will likely never need another air filter.

Yes, K&N filters cost more than the paper air filter that came on your vehicle, but the money you save by not having to replace paper air filters will more than make up for your initial purchase price.

But wait...there's more.

K&N is so confident in their filters, they're guaranteed to perform for up to 10 years or 1 million miles without needing replacement. That’s not a typo—K&N actually guarantees them for 1 million miles.

Easy Installation, Fits Virtually Every Vehicle

You’ve installed an air filter before, right? Nothing to it. K&N filters are no different. They’re available for virtually every car and truck on the road today, and they drop right into your air filter box. It’s a 5-minute job, tops.
