Weapon-R 805-123-101 Dragon Intake System with Polyurethane Foam Filter CARB Exempt

The Weapon-R 805-123-101 Dragon Intake System is a high-performance air intake engineered to maximize engine output through precision construction and purpose-built filtration. Rated "Best Overall Performer" in the Tuner Performance Reports Intake System Showdown, the Dragon Intake outperformed both cold air and short ram intake systems — a testament to Weapon-R's engineering-first approach.

Each Dragon Intake tube is CNC mandrel bent from 6061 aluminum and hand TIG welded to ensure a positive, leak-free seal and precise fitment. Weapon-R engineers carefully match each intake system's tube diameter and length to the engine's displacement, air intake capacity, and target airspeed — optimizing airflow dynamics to unlock the engine's full performance potential.

Key Features:

• 6061 Aluminum Construction — CNC mandrel bent tubing for consistent geometry and optimal flow
• Hand TIG Welded — ensures a positive seal and long-term durability
• Engine-Matched Tuning — tube size and length calibrated to engine displacement, airspeed, and intake capacity
• Dragon Foam Filter — high-density polyurethane foam filter delivers up to 80% more airflow compared to conventional cotton filters, with superior dirt filtration
• CAD-Designed Velocity Stack — flow bench-tested velocity stack increases both air volume and velocity entering the engine
• Cleanable and Rebuildable Filter — Dragon Filter can be fully disassembled for cleaning or foam element color changes, making it reusable
• CARB Exempt — California Air Resources Board compliant for street legal use in all 50 states
• Racing Proven — used in multiple forms of motorsport competition worldwide

The included Dragon Filter is the centerpiece of this intake system, pairing a CAD-designed, flow bench-tested velocity stack with a dense polyurethane foam element that flows significantly more air than cotton gauze alternatives while maintaining excellent filtration efficiency. The filter's modular design allows for routine cleaning and reassembly without replacement, reducing long-term maintenance costs.
