Product Details

The Weapon-R 601-168-101 Secret Weapon Intake is a high-performance short ram air intake system engineered to maximize airflow volume and velocity to your engine. Utilizing a patented dual-velocity design (US Patent #7,263,961B2), this intake system outperforms conventional air intake setups by delivering significantly more air to the combustion chamber.

Patented Dual-Velocity Technology:

At the core of the Secret Weapon Intake is Weapon-R's proprietary airflow engineering, which leverages the Coanda effect and Bernoulli's principle to create two distinct air velocity profiles within a single intake tube. One stream travels faster than the other, increasing the total volume and speed of air delivered to the engine — feeding it up to 3x more air than a conventional factory air intake system.

Key Features:

  • CNC Mandrel-Bent 6061 Aluminum intake pipe — precision-formed for smooth, unrestricted airflow and structural rigidity
  • High-quality polished finish — show-quality mirror shine straight from the factory
  • SW1 Air Filter with tuned velocity stack — increases incoming air velocity while reducing turbulence for more efficient combustion
  • Open-pore, high-density reusable foam filter — washable and reusable for long-term performance and cost savings
  • 1 Million Mile Limited Warranty — backed by Weapon-R's industry-leading coverage
  • Includes all hardware and installation instructions for a complete bolt-on installation
  • Available for over 250 car, truck, and SUV applications

The Secret Weapon Intake is a race-inspired performance upgrade designed and manufactured by Weapon-R Competition Products. All Weapon-R products are developed using computer simulation, modeling techniques, and extensive dyno testing to ensure real-world performance gains.

Note: This is a race-intended product. Verify compliance with local emissions regulations prior to installation.

The website timed out a few times which made it a bit frustrating, other than that, thumbs up!

Fantastic place to buy from. They had the best price for K&N oil filters for my motorbikes which was good enough. Then I ordered on a Saturday via normal shipping...got it Tuesday morning! Definitely going to order more in the future.

Quick and convenient.
