    Genius lies in simplicity. Even your vehicle performs better when things are simple. K&N proved that having developed air intake systems that replace a restrictive factory system with a single aerodynamic tube. The systems are available in two materials. The first one is Polyethylene that is used to produce 57 and 63 series intake systems. The second one is aluminum, and it is the material for the 69 and 77 series intake systems.

    The secret of the K&N high-flow filters lies in the unique filtering media, which doesn't restrict the air flow. It consists of four to six layers of cotton gauze, oiled to improve the filtering capabilities, and sandwiched between pleated aluminum media to retain even more dirt. The crisscrossed cotton fibers capture the dirt particles, providing high air flow. With this, the K&N filters are washable, which means lifelong use, no additional expenses, and no waste.

    Installing the K&N Air Intake system on your vehicle is one of the most simple, as well as most beneficial modifications you can make. A quality performance Air Intake system can provide many benefits, including: Increased horsepower, Increased torque, Increased fuel economy, more aggressive engine sound at higher rpm, and enhancement of the appearance of your engine bay. Cold Air intake allows a smooth flow of air inside the engine. Thereby you can get more power from the engine for the same quantity of fuel. It will greatly help you in economizing on fuel. More over, the Cold Air Intake will also reduce pollution, as less fuel will be used for generating the same amount of power. This is an important benefit as ecological considerations are a major issue in the present times.
