Airaid 721-476 targets the most restrictive portion of the factory intake system: the factory air filter. Airaid 721-476 offers 35% more filter surface area, improves airflow, and increases service intervals. The Airaid 721-476 is constructed with a hand-poured polyurethane casing rather than rubber or Plastisol, so the filter is guaranteed not to shrink, wrinkle, or warp; and, it will retain its snug fit in the factory intake box for the life of the vehicle.
