Product Details

The Weapon-R Secret Weapon Intake (307-121-401) is a high-performance short ram air intake system engineered to maximize the volume and velocity of air delivered to your engine. Unlike conventional intake systems, this unit employs a patented dual-velocity airflow design (USA Patent #7,263,961B2) that leverages the Coanda effect and Bernoulli's principle to create two distinct air streams within a single intake pipe — one moving at higher velocity than the other — resulting in significantly increased air mass flow to the engine.

Key Features:

  • Patented Dual-Velocity Technology: Creates two simultaneous airflow profiles within the intake pipe, optimizing airflow efficiency and increasing air volume delivered to the engine
  • 6061 Aluminum Intake Pipe: CNC mandrel-bent from aircraft-grade 6061 aluminum for precise fitment and unrestricted airflow
  • Show-Quality Polished Finish: Hand-polished to a mirror shine — available in polished finish only
  • SW1 Performance Air Filter: Features a tuned velocity stack to increase air speed and reduce turbulence at the filter inlet
  • Open-Pore High-Density Foam Filter: Reusable and washable design for long-term, cost-effective maintenance
  • CARB Exempt: Emissions-compliant for use in CARB-regulated states
  • 1 Million Mile Limited Warranty: Backed by Weapon-R's industry-leading warranty

The Secret Weapon Intake is a direct bolt-on upgrade over the restrictive factory airbox, designed to improve throttle response and engine sound while adding a show-quality look under the hood. The reusable filter eliminates the ongoing cost of disposable paper filters, making this a practical long-term performance investment.
