Each breather is secured with an O-ring at the heads, while passing through the backing plate into the mouth of the throttle body using proprietary breather tubes. This kit comes with a one-piece backing plate, breather tubes, specially designed filter, filter top, seals, a reservoir and all necessary hardware. The new patent-pending hidden breather backing plate technology is a superior system compared to our original patented system. High-performance filters are constructed from pre-oiled black cotton for improved airflow and filtration. An air inlet with a smooth radius ensures maximum air flow.
