Dinan Cold Air Intake For BMW 325xi

Description

Dinan’s High Flow Intake System consists of an injection molded replacement lid for the stock air box designed to increase overall volume and accommodate a high flow filter element for optimum intake air-flow. The lid is manufactured using a special composite material, chosen specifically for its ability to resist power robbing under-hood heat. The lid also incorporates an O-ring, completely sealing the air box for maximum pressurization and further insulation against heat-soaking, optimizing performance under varying driving conditions. The System also includes a secondary intake duct that scoops up additional cool, oxygen rich air via the factory brake cooling duct, further improving performance as road speed increases.
