DINAN High Flow Intake System – BMW 330i (E46 2001-2006)

DINAN High Flow Intake System – BMW 330i (E46 2001-2006)

The DINAN High Flow Intake System is engineered to improve airflow and throttle response while maintaining factory reliability and fitment. Designed as a complete replacement lid for the stock airbox, this intake increases overall volume and introduces a high-flow filter element to ensure optimum air delivery under all driving conditions.

Manufactured from a heat-resistant composite material, the system effectively shields the intake charge from power-robbing engine bay heat. A precision O-ring seal keeps the airbox fully pressurized, while a secondary duct channels additional cool air from the factory brake cooling duct — providing a continuous supply of oxygen-rich air as speed increases.

Performance Benefits:

• Power Gains: +6 HP / +5 LB-FT (with DINAN engine software)

• Sealed Design: Prevents heat soak and maintains consistent intake temperatures

• Secondary Air Inlet: Draws additional cold air via the brake cooling duct

• Increased Air Volume: Enlarged filter element allows optimal flow

• Heat-Resistant Lid: Composite construction resists under-hood temperatures

• Direct OEM Fit: Utilizes stock mounting points for a clean, factory-like installation

Key Features:

• Injection-molded airbox lid for increased volume and airflow

• High-flow performance filter element included

• O-ring sealed for maximum pressurization and heat insulation

• Quick, bolt-on installation using factory hardware

Vehicle Compatibility:

• BMW 330i (E46) – 2001–2006
