The 63 Series is very similar to the 57 Series, but is for the performance enthusiast looking for the highest flow possible. Like the 57 Series these use a plastic molded intake pipe and also feature a heat shield to keep all engine heat away from the filter. They use the largest conical filter available and will outflow almost any other intake on the market. They are also backed by the Million Mile warranty like all K And N products.
