Weapon-R 307-123-101 Secret Weapon Cold Air Intake Kit Polished Aluminum

The Weapon-R 307-123-101 Secret Weapon Intake is a high-performance air intake system engineered to dramatically increase airflow to your engine. Utilizing the principles of the Coanda effect and Bernoulli's principle, this patented system (US Patent #7,263,961B2) creates two distinct air velocity profiles within the intake pipe — one stream traveling at higher velocity and one at lower — optimizing airflow efficiency for a measurable gain in air mass and volume.

The result is an intake system capable of delivering up to 3x more air to the engine compared to a conventional factory air intake, translating to improved throttle response and engine performance.

Key Features:

• Dual-velocity airflow technology leverages the Coanda effect and Bernoulli's principle for optimized air delivery
• 6061 aluminum intake pipe precision-formed on a CNC mandrel bender for exact fitment and long-term durability
• High-polish show-quality finish enhances engine bay appearance
• Tuned velocity stack air filter reduces turbulence and increases incoming air velocity
• 1-inch thick open-pore high-flow polyurethane foam filter element provides excellent filtration with minimal restriction
• Reusable and washable filter element for long-term cost savings
• 1 Million Mile Limited Warranty backed by Weapon-R
• Available in polished finish only

The Secret Weapon Intake is a direct-fit performance upgrade that installs without modification. Its innovative dual-velocity design has been recognized in head-to-head testing against both cold air and short ram intake systems, establishing Weapon-R as a leading name among performance intake manufacturers.
