• High-quality 6061 aluminum intake pipe, precision-formed using automated CNC mandrel bending for smooth airflow and durability
• Polished finish providing a sleek, show-quality appearance under the hood
• SW1 air filter with a tuned velocity stack designed to boost air velocity while reducing turbulence
• Reusable, open-pore high-density foam filter media for superior filtration and airflow
• Engineered specifically for TRD supercharged Scion tC models to ensure optimal fit and performance
• Over 250 vehicle applications available from Weapon R, demonstrating extensive expertise in performance intake systems
• Backed by a 1 million mile limited warranty, reflecting confidence in product durability and quality

Construction & Design

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

The SW1 air filter features a specially tuned velocity stack that optimizes airflow by increasing airspeed and reducing turbulence as air enters the engine. The filter media is made from open-pore, high-density foam that is washable and reusable, offering both excellent filtration efficiency and airflow capacity.

Performance & Sound

By increasing the volume and velocity of air delivered to the engine, the Secret Weapon Intake improves combustion efficiency and throttle response, particularly beneficial for the TRD supercharged setup. The enhanced airflow can contribute to a more responsive driving experience and potentially improved power delivery. Additionally, the intake imparts a subtle, aggressive induction sound that enhances the auditory feedback of the supercharged engine without being overly loud or intrusive.

Installation & Fitment

The Weapon R Secret Weapon Intake is designed as a direct-fit upgrade for 2007–2010 Scion tC models equipped with the TRD supercharger. Installation is straightforward and typically requires no permanent modifications or special tools beyond basic hand tools. The intake replaces the factory air intake system, utilizing existing mounting points for a secure and precise fit. Detailed instructions are included to guide users through the installation process.
