Weapon-R 304-134-401 Secret Weapon Neo-Ti Short Ram Air Intake System

The Weapon-R 304-134-401 Secret Weapon Intake is a Limited Edition Neo Titanium short ram intake system engineered to maximize air delivery and engine performance. Featuring Weapon-R's patented dual air velocity technology (US Patent #7,263,961B2), this intake system leverages Boyle's Law, the Bernoulli Equation, and the Coanda Effect to create two distinct airflow profiles within a single intake pipe — one high-velocity stream and one lower-velocity stream — working together to feed the engine significantly more air volume than a conventional intake system.

The intake pipe is precision-bent from aerospace-grade 6061 aluminum using an automated CNC mandrel bender, then finished with a Neo Titanium treatment for a distinctive, show-quality gunmetal appearance. The included SW1 Secret Weapon air filter features a tuned velocity stack designed to reduce turbulence and maximize airflow into the throttle body.
