Weapon-R 305-158-301 Secret Weapon Cold Air Intake Kit - Polished

The Weapon-R 305-158-301 Secret Weapon Cold Air Intake is a patented, high-performance air intake system engineered to dramatically increase airflow volume and velocity to the engine. Backed by US Patent #7,263,961B2, this intake utilizes a dual air velocity profile design rooted in the Coanda effect and Bernoulli's principle, delivering up to 3x more air than a conventional factory intake system.

The intake pipe is precision-formed from aircraft-grade 6061 aluminum using an automated CNC mandrel bender, ensuring consistent bends, structural integrity, and a show-quality polished finish. The included SW1 high-performance air filter features a tuned velocity stack that reduces intake turbulence while maximizing air velocity entering the engine. The 1-inch thick open-pore, high-density polyurethane foam filter element offers excellent filtration efficiency and is fully reusable and washable for long-term use.
