• Feeds the engine up to three times more air than the stock intake system
• Precision-bent intake pipe crafted from high-quality 6061 aluminum using automated CNC mandrel bending
• Polished finish for a high-show quality appearance
• SW1 air filter with a tuned velocity stack to reduce turbulence and increase airflow velocity
• Open pore, high-density reusable foam filter media for superior filtration and longevity
• Over 250 applications available for various cars, trucks, and SUVs
• Backed by a 1 million mile limited warranty for long-term peace of mind

Construction & Design

The intake pipe is expertly formed from premium 6061 aluminum, known for its strength, lightweight properties, and excellent heat dissipation. Using an automated CNC mandrel bending process ensures smooth, consistent bends that maintain optimal airflow without restrictions or turbulence. The polished finish not only enhances engine bay aesthetics but also provides corrosion resistance for lasting durability.

The SW1 air filter features a tuned velocity stack that carefully manages airflow to increase velocity while minimizing turbulence, resulting in more efficient air delivery. The filter media is a high-density, open pore foam that is washable and reusable, providing excellent filtration performance and extended service life.

Performance & Sound

By increasing the volume and velocity of air entering the engine, the Secret Weapon Intake supports improved combustion efficiency and throttle response. This results in a more responsive driving experience, especially beneficial for supercharged applications where airflow demands are higher. Additionally, the intake can contribute to a more aggressive induction sound, enhancing the auditory feedback of your Scion tC’s engine.
