Construction & Design

The intake pipe is crafted from premium 6061 aluminum, known for its strength, lightweight properties, and excellent heat dissipation. The pipe is formed using an automated CNC mandrel bending process, which ensures smooth, consistent bends that minimize airflow restrictions and turbulence. The polished finish not only enhances the engine bay aesthetics but also provides corrosion resistance for lasting durability.

The SW1 air filter features a tuned velocity stack design that optimizes airflow dynamics by increasing velocity and reducing turbulence as air enters the intake. The filter media is made from open pore, high-density foam that is washable and reusable, offering excellent filtration without sacrificing airflow. The included heat shield protects the intake from engine heat soak, maintaining cooler intake air temperatures for improved combustion efficiency.

Performance & Sound

The Secret Weapon Intake System is engineered to increase the volume and velocity of air entering the engine, which can improve throttle response and overall engine efficiency. By delivering up to three times more air than the stock intake, it supports enhanced combustion and can contribute to a more responsive driving experience. Additionally, the intake imparts a subtle, sporty induction sound that enhances the driving experience without being intrusive.
