Dinan BMW E46 330i 01-06 High Flow Intake System

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.

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.

Stage 2 Engine Software recommended for optimum performance and drivability.

Features:

• More Power: + 6 HP, + 5 LB-FT (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
