Weapon R Secret Weapon truck and SUV air intake system for 1999 - 2003 Chevy Silverado 1500 5.3L V8

The Secret Weapon intake system is the result of countless hours of testing and tuning of air intake velocity, air mass, and airspeed for each vehicle application. The result is an intake system that performs better than any other cold air intake, but with a short ram. It is made possible by Weapon R's patent-pending speed velocity theory: by creating a higher airspeed in the intake path you increase air mass, and airspeed, which greatly increase horsepower.

This is possible by creating two different paths of airflow, both flowing at different airspeeds, due to the tubing diameter in which the air is traveling. Now when the two different paths of air meet, they create a vacuum, which is where the airspeed starts to multiply, forcing more air into the engine at a higher rate, creating more horsepower.

The Secret Weapon intake systems are carefully CNC mandrel bent out of 6061 aluminum, and then hand TIG-welded in sections to ensure a constant balance in airflow, regulation in airspeed, positive seal, and proper fit. Each one of these intake systems is carefully tuned, by matching the engine displacement, air intake capacity, and airspeed to the intake systems tube size, length, and secondary pathway tubing diameters to maximize the full potential of the Secret Weapon Intake System.

This intake is matched with our newly designed SW1 filter, which provides maximum airflow, with the protection of high quality dense polyurethane foam. Many studies have shown flow rates of up to 80% more air and better dirt filtration with foam filters than the conventional cotton filter. The SW1 main feature is a computer CAD-designed and flow bench tested turbo velocity stack, which greatly increases airflow, airspeed, and air mass into the engine, therefore increasing engine performance. Another one of the great features of the SW1 filters is the capability to be disassembled to be cleaned and then re-assembled after cleanings or to change the color of the foam filtering element.
