This seemingly simple yet very effective approach to the business of improved intake efficiency consists of a replacement lid for the stock airbox 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.


  • More Power: + 8 HP @ 6500 RPM, + 7 LB-FT @ 6500 RPM (coupled w/ engine software)
  • Sealed system for maximum insulation from power robbing heat
  • Additional ram air intake duct for additional air flow
  • Enlarged filter element for optimum flow
