Construction & Design

The intake pipe is crafted from premium 6061 aluminum, chosen for its strength, lightweight properties, and resistance to corrosion. The pipe is formed using an automated CNC mandrel bending process, ensuring smooth, consistent bends that minimize airflow restrictions and turbulence. The polished finish not only enhances the engine bay aesthetics but also provides a protective layer against environmental factors.

The SW1 air filter utilizes a tuned velocity stack that optimizes airflow velocity and reduces turbulence, improving the engine’s volumetric efficiency. The filter media is made from open pore, high-density foam that is reusable and easy to clean, providing long-lasting filtration performance without sacrificing airflow.

Performance & Sound

By increasing the volume and velocity of air entering the engine, the Secret Weapon Intake System supports improved combustion efficiency, which can translate to enhanced throttle response and potential power gains. The design also contributes to a more aggressive intake sound, giving your Scion tC a sportier engine note without excessive drone.

Installation & Fitment
