K&N, formally known as K&N Engineering, Inc., is the world’s leading manufacturer of washable performance air filters and cold air intake systems. K&N manufactures over 12,000 parts for a wide range of makes and models of motorcycles, cars, SUV, trucks, industrial applications, and more. K&N was founded in 1969 and is headquartered in Riverside, California in a complex of 10 buildings compromising approximately 400,000 square feet. K&N also operates facilities in China, England, and the Netherlands.
In the early 1960s, two motorcycle racers, Ken Johnson and Norm McDonald (K&N) developed a revolutionary idea for an air filter—one that could perform under the demands of dusty, dirty off-road environments. After experimenting with different types of filter media, they discovered that an oiled cotton design allowed the filter to capture contaminants efficiently, and also be washed and reused. It was right then and there that the original K&N High-Flow Air Filter was born. Fifty years later, K&N is still dominating the industry with leading filtration technology and innovative products that offer extraordinary protection for virtually every application out there.
What Makes K&N the Best?All K&N products undergo rigorous testing to make sure they adhere to and exceed demanding quality standards. These tests include power, torque, and airflow tests to confirm that the intake products are maximizing power boost while retaining engine safety. The company stands behind its product 100 percent with some of the most extensive warranties in the business – a Million Mile Limited warranty. K&N’s performance air intake systems are designed to improve airflow to the engine by replacing the restrictive factory system with a single aerodynamic tube and highly efficient filter media. The systems are available in two materials. The first is Polyethylene, which is used to produce 57 and 63 series intake systems. The second one is aluminum, which can be found on the 69 and 77 series intake systems.
Advantages of K&N IntakesThe benefits of adding a K&N intake system to your car are plenty. Firstly, it will increase your vehicle’s horsepower and torque, while also improving fuel economy and the appearance of your engine bay. What’s more, it will deliver a satisfying, more aggressive exhaust note at higher RPMs. Each K&N intake includes an oversized filtering unit, which can go up to 100,000 miles between cleanings, unlike paper filters that can become clogged easily and cannot be washed or reused. In other words, with K&N products, you will never have to replace your air filter again.
Why Install an Aftermarket Intake?Internal combustion engines all work as large air pumps. Air goes in, fuel is added, combustion occurs, and air goes out. This means there are two ways of increasing power: getting more air into the engine or making it easier for air to get out of the engine. Your air intake is responsible for filtering air before it enters your engine. Dirty air can damage the engine cylinder walls, so a high-quality filter is a must-have item. With a K&N system or filter, you increase airflow through the filter, which means more air is pulled into the engine. K&N does this without reducing filtration qualities, so your engine will live a long life.
