Weapon-R 301-129-101 Secret Weapon Air Intake Kit Polished Aluminum - 6061

The Weapon-R Secret Weapon Intake (301-129-101) is a high-performance air intake system engineered to significantly increase airflow volume and velocity to the engine. Unlike conventional short ram or cold air intakes, the Secret Weapon utilizes the Coanda effect and Bernoulli's principle to generate two distinct air velocity profiles within the intake pipe — one high-speed stream and one lower-speed stream — working together to deliver up to 3x more air than a stock intake system.

Precision-Engineered Intake Pipe:

The intake pipe is CNC mandrel-bent from aircraft-grade 6061 aluminum for maximum strength and a smooth, unrestricted airflow path. Each pipe is polished to a high-gloss show-quality finish, giving your engine bay a clean, aggressive look. This intake is only available in polished finish.

SW1 High-Performance Air Filter:

The included SW1 air filter features a tuned velocity stack design that increases incoming air speed while reducing turbulence at the filter inlet. The 1-inch thick open-pore, high-density polyurethane foam filtering element delivers exceptional filtration with minimal restriction and is fully washable and reusable — no replacement filters needed.

Key Features:

• Dual Air Velocity Technology — Leverages Coanda effect and Bernoulli's principle for maximum airflow efficiency
• 3x Airflow Increase — Delivers significantly more air volume than conventional intake systems
• 6061 Aluminum Intake Pipe — CNC mandrel-bent for smooth bends and optimal flow
• High-Gloss Polished Finish — Show-quality appearance straight out of the box
• Tuned Velocity Stack Filter (SW1) — Reduces turbulence and maximizes incoming air speed
• Reusable Open-Pore Foam Element — 1-inch thick, washable, and long-lasting
• US Patented Design — Patent No. 7,263,961 B2
• 1 Million Mile Limited Warranty — Industry-leading coverage

The Weapon-R Secret Weapon Intake is a direct-fit performance upgrade backed by a US patent and a 1 million mile limited warranty, making it one of the most confidence-inspiring intake systems available for performance enthusiasts.
