Weapon-R 307-166-101 Secret Weapon Performance Air Intake Kit Polished

The Weapon-R 307-166-101 Secret Weapon Intake is a patented high-performance air intake system engineered to dramatically increase airflow volume and velocity to the engine. Backed by US Patent #7,263,961B2, this intake leverages two well-established physics principles — the Coanda effect and Bernoulli's principle — to create a dual air velocity profile within the intake pipe, delivering measurably more air to the combustion chamber than a conventional OEM intake system.

How It Works:

By generating two distinct air velocity streams simultaneously — one at higher speed and one at lower speed — the Secret Weapon Intake optimizes airflow efficiency and increases total air mass delivered to the engine. This dual-velocity approach is capable of supplying up to 3x more air than a stock air intake system, supporting improved throttle response and engine output.

Key Features:

• Patented Dual-Velocity Technology — US Patent #7,263,961B2; utilizes Coanda effect and Bernoulli's principle for maximum airflow efficiency
• CNC-Mandrel Bent 6061 Aluminum Intake Pipe — precision-formed from aircraft-grade aluminum for strength, durability, and a smooth interior bore
• High-Gloss Polished Finish — show-quality mirror polish; available in polished finish only
• SW1 High-Performance Air Filter — features a tuned velocity stack design to increase incoming air velocity and reduce turbulence
• 1-Inch Thick High-Flow Polyurethane Foam Filter Element — open-pore, high-density construction; fully reusable and washable for long service life
• 1 Million Mile Limited Warranty — Weapon-R stands behind the durability of this system with an industry-leading warranty

The Secret Weapon Intake installs in place of the restrictive factory air intake system and is constructed entirely from premium materials for a lasting performance upgrade. The polished aluminum pipe and velocity-tuned filter work together to reduce intake restriction while giving the engine bay a clean, aggressive appearance.
