K&N lifetime replacement air filters are designed to increase horsepower and acceleration while providing excellent filtration. These filters are custom designed to fit into your existing factory air box. Their drop in design means adding performance is simple. Simply remove the disposable air filter and replace it with a K&N, there is NEVER any cutting or fitting required. Our stock replacement air filters for street vehicles are covered by our famous K&N Million-Mile Limited Warranty and will be THE LAST AIR FILTER YOUR VEHICLE WILL EVER NEED.
6,000 + (and growing) factories in our existing network are eager to make it for you.
When it comes to selling in stock products, we are no difference from many other Internet retailers, but we take pride in going extra miles to do something special for you: Have some products custom made for you.
We cannot do everything, but we usually can accommodate a certain changes in product options such as color, size, material, or minor design twist. We primarily work with vendors or factories, not individual artist or craftsman. For custom made products, we usually only cater to bulk size order that meets the minimum quantity requirement of a single factory run. Don't be shy. Ask. What we can accomplish may surprise you!
