Product Description

The Weapon*R Secret Weapon (SW) Intake stands out as a top-performing air intake system, proven in a Tuner Performance Reports Magazine showdown where it surpassed both Cold Air and Short Ram intakes, reinforcing its reputation among performance enthusiasts. Its innovation lies in applying advanced fluid dynamics, specifically the Coanda effect—which allows airflow to follow curved surfaces—and Bernoulli's principle—which links increased airspeed to decreased pressure—to create two distinct airflow streams within the intake pipe: one high-velocity and one low-velocity, working together to significantly improve airflow efficiency and volume. This dual-velocity system enables the SW Intake to deliver up to three times more air into the engine compared to conventional systems, resulting in better combustion and increased performance. The intake is precision-engineered from high-quality 6061 aluminum using a CNC mandrel bending process, ensuring durability, smooth airflow, and an attractive polished finish, while its specially designed air filter—featuring a tuned velocity stack and a 1-inch thick high-flow polyurethane foam element—minimizes turbulence, maximizes airspeed, and maintains excellent filtration with minimal restriction, making the entire system a well-balanced combination of power, engineering, and design.
