CVF's dual-filter, colar air intake is designed with an unique equal length tube design that features an H-pipe balance tube for increased airflow and velocity, resulting in improved throttle response. To keep your air clean, this kit has two massive 7" conical high-performance air filters, which increase airflow up to 45% above stock intakes. Plus, the filters are washable and reusable. These 8-layer dry air filters will capture more contaminants without sacrificing performance. No assembly is required for the lower half of the factory air box, which is encased in a heavy-duty 16-gauge heat shield. The top-mounted shield design allows for hassle-free installation using only standard factory mounting locations.
