Weapon-R 301-158-101 Secret Weapon Cold Air Intake System Polished Aluminum

The Weapon-R 301-158-101 Secret Weapon Intake is a high-performance cold air intake system engineered to maximize airflow volume and velocity to your engine. Utilizing Weapon-R's patented dual air velocity profile technology (US Patent #7,263,961B2), the system creates two distinct airflow streams moving at different speeds simultaneously — leveraging the Coanda effect and Bernoulli's principle to dramatically increase the volume of air delivered to the engine compared to a conventional factory intake.

Key Features:

• Patented dual-velocity airflow design delivers up to 3x more air than a standard OEM intake system
• CNC mandrel-bent 6061 aluminum intake pipe — formed on an automated mandrel bender for smooth, restriction-free bends
• High-gloss polished finish — show-quality appearance straight from the box; available in polished only
• SW1 air filter with tuned velocity stack — increases air velocity while reducing turbulence at the filter inlet
• Open-pore, high-density foam filter media — reusable and washable for long-term use
• CARB Exempt (EO# D-489-3) — emissions compliant and legal for use in California
• 1 Million Mile Limited Warranty — backed by Weapon-R's industry-leading coverage
• Direct bolt-on installation — no cutting or modification required

The Secret Weapon Intake is tuned and dyno-tested to improve throttle response, acceleration, and engine sound. The polished aluminum pipe adds a clean, aggressive look to any engine bay. Whether you're building a dedicated track car or simply want a noticeable street performance upgrade, the Weapon-R Secret Weapon Intake is a proven first-modification choice.
