• Lasts up to 100,000 miles before service is required (depending on driving conditions)

K&N 57 Series Generation II Air Intake Kits are built for many different vehicles and represent a dramatic improvement over a K&N OE replacement filter alone. These kits use only nonmetallic, rotationally molded tubes that can reduce air temperature and decrease intake sound over a metal tube. Restriction can exist between an air filter and the engine, reducing the benefit of a K&N air filter. The weakest link in the air flow chain robs a vehicle of its natural horsepower. Often that weak point is the factory air path leading to the engine. K&N air intake kits virtually eliminate air path restriction by replacing the air filter and the entire air path to the engine. The aerodynamically engineered tube drives a massive amount of air into an engine, which translates into power.

• Million-mile limited warranty
• Replaces OEM filter and air box
• Air filter is washable and reusable
• Works with OEM computer systems
• Designed to use factory holes and mounting points whenever possible
• Most are CARB exempt and street legal in all 50 states

A truly state-of-the-art air intake system, the K&N 57 Series Generation II Air Intake Kit kits features the largest conical-shaped, high-flow air filter that can be fit into the engine compartment using factory holes and mounting points. This extra filter size provides even more air flow at lower restriction than a standard K&N OE replacement filter, which is limited to the size of the factory air box. The over-sized air filter also captures and holds more dirt, increasing the service life before a cleaning is required (up to 100,000 miles). When possible, the filter is isolated from high engine temperature by a heat shield designed to lower the temperature of the air entering the engine, which increases horsepower. Next, the filter is attached to a rotationally molded tube made from interlaced, high-density polyethylene. This process allows K&N to precisely shape the tube in order to reduce turbulence and accelerate air flow into the engine. This is why some of our tubes have unique shapes that are specifically engineered for each application. Finally, the tube is connected to the engine with adapters made from high-strength materials, such as silicon and reinforced nylon, ensuring long life.
