K&N is the leader and originator of great range of high performance air filters that provide maximum power and excellent protection for any type of vehicle. With state of the art design and enhanced functionality of their air filters, air induction kits and oil filters, K&N stand out as one of the leading manufactures and distributors of products of the kind. All of K&N’s products are the result of continuous scientific research that goes on at the company’s facilities and in independent laboratories. Their high-end test equipment enables K&N to subject all their products to extensive tests.

All K&N air filters are designed around the concept that the primary function of an air filter is to deliver high airflow whilst offering superior dirt protection. Increased airflow translates into enhanced horsepower and throttle response, or, in other words, increased engine performance. High filtration levels are critical to long engine life. K&N air filters are designed to achieve virtually unrestricted airflow while ensuring optimal filtration levels.

K&N’s OE replacement air filters are handmade in the United States and the United Kingdom using only the finest materials. These filters are washable and reusable. Laboratory tests have shown that K&N air filters can be washed and re-oiled more than one hundred times and still perform up to specification.

K&N’s high performance air intake kits guarantee a consistent increase in horsepower. This is achieved with a large conical open element air filter, which provides a larger surface for huge increases in airflow. The same oversized air filters allows for more dirt to be captured and held. This translates into a longer service lifespan, with an overall of up to 100,000 miles for air intakes before a cleaning is required, depending largely on driving conditions.

K&N’s air intake tubes are either molded high-density polyethylene tubes or aluminum power coated or anodized ones. The former provide the highest level of flexibility in air intake design, as well as the best possible horsepower numbers, while the latter offer power with a more stylish look.

K&N is the inventor of the world’s first air filter with a million-mile limited warranty. This warranty is applicable to all of K&N’s high-flow air intake systems, which are built with the finest materials and are the result of some of the most documented engineering processes.

Durability and easy removal are the most important features of K&N oil filters and the reason why they are becoming increasingly popular among consumers. K&N’s premium automotive oil filter was initially developed for demanding auto race applications but it is now highly sought after for a wide range of vehicles. K&N oil filters use resin impregnated cellulose filter media, which allows for both outstanding filtration and higher flow rates.

The vast majority of K&N products are easy to install as a result of kits being engineered to use existing factory holes and mounting points. Most of K&N’s air intake kits do not require any cutting or drilling. Installation can be completed in less than ninety minutes with a screwdriver, pliers and a ratchet set.
