Weapon-R 307-157-101 Secret Weapon Cold Air Intake Kit - Polished

The Weapon-R 307-157-101 Secret Weapon Intake is a high-performance cold air intake system engineered to maximize engine airflow through patented dual-velocity technology (US Patent #7,263,961B2). By leveraging the Coanda effect and Bernoulli's principle, the Secret Weapon Intake creates two distinct air velocity profiles within the intake pipe — one moving at a higher speed than the other — delivering significantly greater air volume and velocity to the engine compared to a conventional intake system.

Key Features:

• Patented dual air velocity profile design increases air volume and speed to the engine (US Patent #7,263,961B2)
• Intake pipe precision-bent from high-quality 6061 aluminum on an automated CNC mandrel bender
• High-gloss polished finish — show-quality appearance for the engine bay
• Includes the SW1 air filter with a tuned velocity stack to boost airflow velocity and reduce turbulence
• Open-pore, high-density reusable foam filter for long service life
• 1 Million Mile Limited Warranty
• Available finish: Polished only

The Secret Weapon Intake is a direct-fit performance upgrade designed to improve throttle response and engine breathing over the stock air intake system. The reusable foam filter reduces long-term maintenance costs while the polished aluminum pipe adds a clean, professional look under the hood.
