# Dinan 01-06 BMW 325Ci E46 325 Airbox Kit

Dinan's High Flow Intake System consists of an injection-molded replacement lid for the stock airbox 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.

-   More Power: + 9 HP @ 6500 RPM, + 8 LB-FT @ 6500 RPM (coupled w/ engine software)
-   Sealed system for maximum insulation from power robbing heat
-   Additional secondary inlet for additional air flow
-   Enlarged filter element for optimum flow
