Weapon-R 305-172-101 Secret Weapon Dual-Velocity Air Intake System

The Weapon-R Secret Weapon Intake (305-172-101) is a patented, high-performance air intake system engineered to dramatically increase the volume and speed of air delivered to your engine. Unlike conventional intake systems, the Secret Weapon leverages the Coanda effect and Bernoulli's principle to generate two distinct air velocity profiles within the intake pipe — one high-speed stream and one lower-speed stream — working together to optimize airflow efficiency and deliver up to 3x more air than a stock intake system.

The intake pipe is precision-formed from 6061 aircraft-grade aluminum using an automated CNC mandrel bending process, ensuring smooth, consistent bends with no kinks or flow restrictions. The pipe is finished to a high-gloss polished show-quality surface that looks as good as it performs.
