This seemingly simple yet very effective approach to the business of improved intake efficiency consists of a replacement lid for the stock air box designed to increase overall volume and accommodate a high flow filter element. The lid is molded from a special composite material, chosen for its ability to resist power robbing under-hood heat. The lid also provides for a completely sealed air box, maximizing pressurization for optimum performance. The addition of the Ram Air Intake Duct maximizes intake system efficiency for even greater improvements in overall performance. May be installed with or without the ram air intake duct. Stage 2 software highly recommended.
