Weapon-R 301-157-101 Secret Weapon Air Intake Kit - Polished

The Weapon-R Secret Weapon Intake (301-157-101) is a patented, high-performance air intake system engineered to significantly increase air volume and velocity delivered to your engine. Unlike conventional short ram or cold air intakes, the Secret Weapon uses a proprietary dual-velocity technology rooted in two well-established physics principles — the Coanda effect and Bernoulli's principle — to create two simultaneous air velocity profiles within a single intake pipe. The result is a substantial increase in air mass flow, capable of delivering up to 3x more air to the engine compared to a standard air intake system.

Key Features:

• Patented Dual-Velocity Technology — US Patent #7,263,961B2; creates two air velocity profiles for maximized air volume and flow efficiency
• CNC Mandrel-Bent 6061 Aluminum Pipe — precision-formed on an automated mandrel bender for accurate fitment and a durable, lightweight structure
• High-Polish Finish — show-quality polished aluminum for an aggressive, clean engine bay appearance
• SW1 Tuned Velocity Stack Air Filter — specifically designed to increase air velocity and reduce turbulence at the filter inlet
• 1-Inch Thick High-Flow Polyurethane Foam Element — open-pore, high-density reusable foam provides excellent filtration with minimal airflow restriction
• CARB Exempt — compliant for use in California and all 50 states
• 1 Million Mile Limited Warranty — backed by Weapon-R's industry-leading warranty program

The Secret Weapon Intake is a direct-fit, bolt-on upgrade that delivers improved throttle response, enhanced engine sound, and increased airflow efficiency. The reusable foam filter element eliminates the ongoing cost of disposable paper filters, making this a long-term performance investment for enthusiasts.
