Weapon-R 301-139-101 Secret Weapon Polished Aluminum Air Intake Kit

The Weapon-R Secret Weapon Air Intake (MPN: 301-139-101) is a performance cold air intake system engineered to significantly increase airflow volume and velocity to your engine. Using Weapon-R's proprietary dual air velocity profile technology, the intake simultaneously generates two distinct airflow streams — one moving at a higher speed than the other — working together to maximize the volume and speed of air delivered to the combustion chamber.

Key Features:

• Dual velocity airflow technology — creates two distinct air velocity profiles to optimize both air volume and speed entering the engine
• Premium 6061 aluminum intake pipe — precision-formed on an automated CNC mandrel bender for smooth, consistent bends that minimize turbulence and airflow restriction
• High-gloss polished finish — show-quality mirror polish for an aggressive underhood appearance
• SW1 air filter with tuned velocity stack — engineered to further increase inlet air velocity while reducing turbulence at the filter entry point
• Reusable open-pore high-density foam filter media — washable and reusable for long service life and low maintenance cost
• 1 Million Mile Limited Warranty — industry-leading warranty coverage backed by Weapon-R
• USA Patent No. 7,263,961 B2 — proprietary dual velocity intake technology
• Available across 250+ vehicle applications including cars, trucks, and SUVs

The Secret Weapon Intake installs as a direct bolt-on replacement for the factory air intake system, requiring no permanent modifications and typically completed with basic hand tools. The polished aluminum pipe and SW1 velocity stack filter combine to deliver improved throttle response, a more aggressive induction sound, and enhanced engine breathing efficiency over the restrictive stock airbox.
