Filter Options

The Secret Weapon Air Intake comes with the SW1 air filter featuring a tuned velocity stack that enhances airflow dynamics. The filter uses a high-density, open-pore foam media that is reusable and designed for extended service life. The intake system is available in two finishes:

• Polished aluminum (Part # 307-168-101)
• Stealth black powder-coated aluminum (Part # 307-168-109)

Construction & Design:

Crafted from premium 6061 aluminum, the intake pipe is precision-formed using an automated CNC mandrel bending process to ensure smooth airflow and structural integrity. The polished finish is achieved through meticulous polishing techniques, providing a high-quality, show-ready appearance. The stealth black option features a durable powder-coated finish that resists corrosion and complements aggressive engine bay aesthetics.

The design philosophy centers on creating two distinct air velocity profiles within the intake tube, allowing one stream of air to travel faster than the other. This innovative approach increases the total volume and speed of air delivered to the engine, feeding it up to three times more air than conventional intake systems.

Performance & Sound

By significantly increasing airflow and reducing intake restrictions, the Secret Weapon Air Intake enhances engine responsiveness and efficiency. The tuned velocity stack and optimized airflow path contribute to a smoother, more efficient air charge, which can improve throttle response and overall engine performance. Additionally, the intake imparts a subtle, aggressive induction sound that enhances the driving experience without being overpowering.

Installation & Fitment:

The Weapon R Secret Weapon Air Intake is designed as a direct bolt-on replacement for the factory air intake system on compatible vehicles. Installation requires no permanent modifications and can typically be completed with basic hand tools in under an hour. It fits 2005–2024 Chrysler 300C, Dodge Challenger, Charger, and Magnum models equipped with 5.7L Hemi and 6.1L SRT8 engines. Note that this intake does not fit 2011–2024 6.4L SRT8 models.
