How does the K&N 63 intake series increase horsepower? By eliminating airflow obstruction in your engine. Restriction of air flow between an air filter and an engine robs even the most powerful engine of horsepower. K&N air intake kits virtually eliminate air path restriction by replacing the standard air filter and the entire air path to the engine. The aerodynamically engineered conduit drives a massive amount of air into an engine, which translates into power. This conduit begins with an oversized conical high-flow air filter. This larger filter can fit into the engine compartment using factory holes and mounting points because it replaces your stock intake tube, and air box. This provides more airflow at lower restriction than a standard filter, limited by the size of the factory air box. 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 also isolated from high engine temperature by a heat shield designed to lower the temperature of the air entering the engine, which increases horsepower. The filter attaches to a rotationally molded tube made from nonmetallic interlaced high density polyethylene (HDPE). This allows for precision shaping of the tube to reduce turbulence and accelerate airflow into the engine. This is why some K&N tubes have unique shapes or indentations that are specifically engineered for each engine configuration. Finally, the tube is connected to the engine with adapters made from high strength materials such as silicon and reinforced nylon and ensures long life. Put all this together and you have the best high-flow intake system available today.
