With the Filtercharger^®, a special cotton fabric is sandwiched between the pleated aluminum screen wires. The pleated design provides five times more filtering surface over the element circumference. The cotton/screen wire filter media is then saturated with a formulated air filter oil. Acting like a fluid curtain, this oil attracts particles of dirt and debris which build up on the outside of the filter. This buildup of dirt particles suspended in oil creates more and more irregular passages that actually create an additional filtering barrier with each use. In most cases, up to 1/8" of dust can cover a Filtercharger^® before performance is significantly affected. On a street driven automobile, a Filtercharger^® can last up to 50,000 miles before service is required.

Then, because it's made of resuable materials, you can just clean it, apply fresh K&N^® Filter Oil and re-install. This process is accomplished with the use of the Recharger Filter Care Service Kit. The K&N^® Recharge Filter Care Service Kit (shown below) works to dissolve the dirt build up and old filter oil, and can be washed away with water. It completely restores air flow efficiency so your Filtercharger^® performs like new! K&N^® has developed environmentally friendly cleaning products designed to effectively clean the filter without harming the environment through the absence of fluorocarbons.
K&N^® recommends servicing your filter every 50,000 to 100,000 miles on street driven vehicles.

More air flow, increased horsepower, long lasting performance, our Million Mile Warranty even after 35 years, the K&N^® Filtercharger^® is still on the cutting edge of air filtration technology.

Please note: We do not have an application for every vehicle. The Recharge Kit listed below is a compliment to an air filter and does not take the place or is meant to be an air filter.
