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 addition of the Ram Air Intake Duct maximizes intake system efficiency for even greater improvements in overall performance.
Only for 2003 - 2005 models. May be installed with or without the Ram Air Intake Duct. Stage 2 software highly recommended.
