The 63 Series Air Intake Kit starts with the largest conical shaped high-flow air filter that can fit into the engine compartment while using factory holes and mounting points. This extra filter size provides even more airflow at lower restriction than a standard K&N OE replacement filter that 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 (up to 100,000 miles).

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 K&N attach the filter to a rotationally molded tube made from interlaced high density polyethylene. This process allows K&N to precisely shape the tube to reduce turbulence and accelerate airflow into the engine. Finally the tube is connected to the engine with adapters made from high strength materials such as silicone and reinforced nylon and ensures long life. Put all this together and you have the best high-flow intake kit available today.
