How does the K & N filter?
Air filter 101
Engines producethe power to cause a mixture of fuel and air. The air filter is responsible for filtering out dirt particles, while a free flow of air around the engine can "breathe." A dirty filter of land, is the loss of power and fuel economy.
Most air filters used his role as a filter medium. Most cars need the filter to be revised or amended at any 10,000 20,000 miles, when the filter is dirty, is removed and replaced.

Benefits of K & N Filters
Environmental Benefits
Paper air filters can not be recycled, you throw everything. K & N filter was a hard life of the car and cleaning kit used cartons and plastic bottles can be recycled.
Cost Benefits
The savings can be dependentApplication. And I tried, K N filter in our 1996 Honda Accord. The recommended retail price for the K & N filter is about $ 43. (My sample was 31 for free courtesy of K & N) filter cards from $ 19 to $. Honda recommends a change in miles-Filter 15000, so for a do-it-yourself, like me, K & N filter and a cleaning kit to take care of itself after two changes, or about two years. For people who have been waiting for their vehicle by the dealership agreement, theInstalling a K & N could pay for itself in a shift of just one.
In the real world performance
This is the reaility: I am not as careful as I should I change my car "is the air filter. By the time I get around it is, the filter is clogged with dirt, as a rule - and that means more than I pump. The K & N longer service intervals means you happily ignore that, without adverse effects.
