Dinan High Flow Intake System - 2003-2005 BMW Z4

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.SpacificationBrand: Dinan Dinan Point Value: 1.0 Emission Code: 0.5 Factory Rated HP: Cold Air Intake Factory Rated Torque (lb-ft): California Proposition 65 Peak HP: 3 Peak HP Gain: 8 Peak Torque (lb-ft): 24 Peak Torque (lb-ft) Gain: 8 @ 6500 RPM Product Type: 7 @ 6500 RPM Warning: 5.9 Warranty: 12Associated Comments: Not compatible with the Z4 3.0i (E85) from 2006-2008.
