Weapon-R 307-201-101 Secret Weapon Air Intake Kit - Polished

The Weapon-R 307-201-101 Secret Weapon Intake is a high-performance cold air intake system engineered to significantly increase airflow volume and velocity to your engine. Unlike conventional intake systems, the Secret Weapon's patented design (US Patent #7,263,961B2) leverages the Coanda effect and Bernoulli's principle to generate two distinct air velocity profiles simultaneously within the intake pipe — one stream moving at a higher velocity than the other. This dual-velocity approach optimizes airflow efficiency and delivers up to 3x more air to the engine compared to a standard factory intake.

Key Features:

• Patented dual air velocity profile technology using Coanda effect and Bernoulli's principle
• Intake pipe precision-bent from high-quality 6061 aluminum using an automated CNC mandrel bender
• High-polish show-quality finish — Only available in polished
• SW1 air filter features a tuned velocity stack to increase air velocity and reduce turbulence
• 1-inch thick open-pore, high-density reusable polyurethane foam filter element for superior filtration with minimal restriction
• Reusable and washable filter — no disposable filter replacements needed
• Backed by Weapon-R's 1 Million Mile Limited Warranty

The Secret Weapon Intake's innovative design has been recognized in independent testing — in an intake system comparison by Tuner Performance Reports Magazine, Weapon-R intake systems outperformed both cold air and short ram intake designs. The result is a direct bolt-on performance upgrade that adds a polished, aggressive look to your engine bay while delivering real, measurable gains in engine breathing efficiency.
