These kits are truly state-of-the-art. K&N starts with the largest conical shaped High-Flow air filter that will fit into the engine compartment while using factory holes and mounting points. The oversize 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 they attach the filter to a rotationally molded tube made from interlaced High Density Polyethylene. This precisely shapes the tube to reduce turbulence and accelerate airflow into the engine. This is why the 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.
