It replaces the restrictive factory air filter and air intake housing with a fully enclosed, injection-molded air box designed to reduce airflow restriction and help smooth and straighten incoming air.\u003c\/p\u003e\n\u003cp\u003eBy allowing the engine to draw in more air than the factory filter assembly, this K\u0026amp;N performance airbox is designed to support increased usable power and acceleration throughout the engine’s RPM range. The air box connects to the factory air intake hose and uses the previous air box space for installation.\u003c\/p\u003e\n\u003cp\u003eA removable lid provides access to the filter when cleaning is required, while the installation is described as relatively easy using commonly available tools.
