Weapon-R 304-139-101 Secret Weapon Cold Air Intake Kit Polished Aluminum

The Weapon-R 304-139-101 Secret Weapon Intake is a performance cold air intake system engineered to significantly increase airflow volume and velocity to your engine. Weapon-R's patented dual-velocity airflow technology is rooted in three fundamental laws of physics — Boyle's Law, the Bernoulli Equation, and the Coanda Effect — creating two distinct air velocity profiles that work together to deliver up to 3x more air than a conventional factory intake system.

The intake pipe is precision-bent from high-quality 6061 aircraft-grade aluminum using an automated CNC mandrel bender, then polished to a high-gloss show-quality finish. This construction ensures smooth, unrestricted airflow with long-term durability. The included SW1 air filter features a tuned velocity stack designed to maximize air velocity while minimizing turbulence at the filter inlet.

Key Features:

• Dual air velocity profile technology increases engine airflow up to 3x over stock
• Precision-bent 6061 aluminum intake pipe — CNC mandrel formed for smooth bends
• High-gloss polished finish — show-quality appearance under the hood
• SW1 air filter with tuned velocity stack for reduced turbulence and increased velocity
• Open-pore, high-density reusable foam filter element — washable and re-oilable
• Available in polished finish
• 1 Million Mile Limited Warranty
• Compatible with a wide range of cars, trucks, and SUVs

The Weapon-R Secret Weapon Intake is a direct-fit performance upgrade that delivers improved throttle response and an enhanced engine intake sound. The reusable foam filter eliminates the ongoing cost of disposable paper filters, making it a smart long-term investment for performance enthusiasts.
