Weapon-R 304-127-401B Secret Weapon Air Intake System - Polished

The Weapon-R 304-127-401B Secret Weapon Intake is a high-performance air intake system engineered to dramatically increase airflow volume and velocity to your engine. Using patented technology rooted in three fundamental laws of physics — Boyle's Law, the Bernoulli Equation, and the Coanda Effect — this system creates two distinct air velocity profiles traveling at different speeds simultaneously, delivering up to 3x more air to the engine compared to a conventional factory intake.

The intake pipe is precision-formed from high-quality 6061 aluminum using an automated CNC mandrel bender, then polished to a show-quality mirror finish. The included SW1 air filter features a tuned velocity stack design that maximizes incoming air velocity while minimizing turbulence for smooth, unrestricted flow.

Key Features:

• Patented dual-velocity airflow technology (US Patent #7,263,961B2) delivers up to 3x the airflow of stock intakes
• Intake pipe constructed from 6061 aluminum via CNC mandrel bending for precise fitment
• High-gloss polished finish — only available in polished
• SW1 air filter with tuned velocity stack reduces turbulence and increases air velocity
• 1-inch thick, open-pore, high-density reusable polyurethane foam filter element
• Easy to clean and re-oil — no replacement filters needed
• Backed by Weapon-R's 1 Million Mile Limited Warranty
• Fits a wide range of cars, trucks, and SUVs
