Weapon-R 843-111-101 Dragon Air Intake Filter 4-Inch Polished with Coupler and Clamp

The Weapon-R 843-111-101 Dragon Air Intake Filter is a high-performance, universal conical air filter featuring a polished cage, dense open-cell polyurethane foam filtration element, and an internal CAD-designed velocity stack. Includes a coupler and clamp for a complete bolt-on installation. The Dragon filter is rated as a top-performing aftermarket intake filter, outperforming cold air and short ram intake systems in independent testing.

Key Features:

• 4-Inch OD inlet opening with a 6-inch width and 6-inch height — compact but high-flowing design
• Open-cell polyurethane foam filtering element provides high airflow even as it collects contaminants, unlike traditional cotton gauze filters
• Internal tuned velocity stack — CAD-designed and flow-bench tested to increase air velocity, air mass, and airspeed entering the engine
• Polished cage construction for a clean, aggressive underhood appearance
• Washable and reusable — the foam element can be removed, cleaned, and reassembled, eliminating the need for replacement filters
• Includes coupler and clamp for straightforward installation on compatible intake systems
• Universal fitment — compatible with a wide range of aftermarket and OEM intake piping
• Not CARB legal — not for sale or use in California

The Dragon Air Intake Filter is engineered to complement Weapon-R intake systems and other aftermarket setups. Its open-cell foam technology allows airflow to continue around captured debris, maintaining strong flow rates even when the filter is dirty. The velocity stack geometry further optimizes air delivery for maximum engine performance potential.
