Starting with the largest conical-shaped, high-flow air filter that will fit into the engine compartment using factory holes and mounting points, K&N 63 Series Aircharger Performance Intake Kits are truly state of the art. 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 oversized air filter also captures and holds more dirt, increasing the service life before a cleaning is required. 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 for a precisely shaped tube to reduce turbulence and accelerate air flow into the engine. This is why some of the intake tubes have unique shapes or indentations 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. Put all this together, and you have the best high-flow intake system available today.
