REDUCES WASTE

Over 100 million disposable air filters and their packaging waste end up in landfills each year. Choosing a washable, reusable product that lasts for the lifespan of your vehicle helps to reduce unnecessary waste.

I used K&N filters in my last 6 vehicles including my current three. I like the added power I get from the filters and the ease of maintenance.

The Original Oiled Filter Design

CUSTOM COTTON FILTER MEDIA

Four or six layers of pleated cotton filter media act as a physical barrier to contaminants, with pleats specifically engineered to provide a large capturing area.

THE MAGIC SAUCE - RED 201 FILTER OIL

The original red filter oil is what separates K&N filters from the pack. The tacky oil helps trap—and hold—dirt and contaminants, keeping them in the filter and out of your engine.
