Washable & Reusable K&N Filters
K&N Air Filters are designed differently. These filters have multiple layers of an oil cotton fabric to capture debris. The fabric is then surrounded in a pleated aluminum mesh. This concertina shape increases the surface area available to filter. A K&N Air filter is able to maintain its performance throughout its life, rather than decreasing like traditional filters.
It does this by capturing contaminants in the fibers of the filter and then holding them in suspension in the oil. Inch for inch, when compared with traditional-style filters, a K&N replacement has as much as a 300% in airflow.
Longer lasting, better for the environment
K&N Air filters will also last the lifespan of your vehicle. They're backed by a limited 1,000,000 mile guarantee. The filter is washable and reusable, using a kit available from the manufacturer. To extend the lifespan of your air filter wash and re-oil between every 30,000 - 50,000 miles. In the long run, you should save money fitting one of these filters versus regularly replacing a paper one.
The K&N website claims that you’ll see as much as a 4% increase in horsepower and torque. This video on YouTube demonstrates the difference, as tested on a dyno, just by fitting a new K&N air filter. The gains are solid!
Performance and Universal Filters
K&N also produce universal clamp-on filters in round, tapered, dual flange and oval shapes. Perfect for your next build. They also manufacturer cold air intake kits that feature a heat shield and MAF sensor mount. These kits offer improved airflow over standard factory set-ups. When purchasing your filter, I recommend you pick up a cleaning and re-oiling kit.
