K&N Air Filter Reviews
Close
Designed to increase horsepower and acceleration while providing excellent filtration, K&N panel air filters are washable and reusable and are custom designed to fit into your existing factory air box. Their drop-in design means adding performance is simple. With most vehicles you simply remove the disposable air filter and replace it with a K&N. This permanent, high performance filter can be cleaned, re-oiled, and used many times over. These low restriction air filters allow the engine to breathe more freely, which means better throttle response and approximately 1-3HP gained throughout the rev range. K&N provides panel filter choices for use in many different types of vehicles including racing applications as well as everyday driving. Many people do not realize that their vehicle has a panel filter as they are often hidden in recesses that may not be noticed on a standard vehicle. If it happens that your car breaks down, the clear plan is installing a high performance OEM or replacement component to restore your vehicle in ideal condition. The dependability and solid performance that go along with having a well-made vehicle are good reasons for the purchase of replacement and aftermarket components with equal value; high-quality parts don't have to cost an arm and a leg.
