Weapon R Twin Throttle Body Secret Weapon Intake Nissan 370z 2009-2020 / Infiniti G37 2008-2013 | 304-140-101

Unlock the full potential of your engine with the Weapon-R Secret Weapon Intake (SW Intake), a revolutionary air intake system engineered to deliver maximum airflow, increased horsepower, and cutting-edge performance. Designed using advanced aerodynamic principles, this intake system outperforms traditional cold air and short ram intakes—making it a top choice for serious enthusiasts.

Recognized in performance testing, Weapon-R intake systems have proven their ability to outperform conventional designs, giving drivers a measurable edge in both power and efficiency.

Advanced Airflow Technology

At the core of the Secret Weapon Intake is a unique design that utilizes the Coanda effect and Bernoulli’s principle to dramatically improve airflow dynamics. By creating dual-velocity air streams, this system increases both the speed and volume of incoming air—helping your engine breathe more efficiently under all driving conditions.

The result is a significant increase in air mass delivery, with the ability to provide up to 3x more airflow compared to standard intake systems.

Precision Engineering & Premium Construction

The intake piping is constructed from high-quality 6061 aluminum, formed using precision mandrel bending for optimal airflow and durability. A polished finish enhances engine bay aesthetics while maintaining long-term corrosion resistance.

High-Performance Air Filter System

The included Secret Weapon air filter is engineered for maximum efficiency:

• Integrated velocity stack design reduces turbulence
• High-flow polyurethane foam filter ensures superior filtration
• 1-inch thick reusable element allows easy cleaning and long service life
• Maintains high airflow while protecting your engine
