Overview

The Weapon R Secret Weapon Intake is designed to maximize air intake volume by utilizing the Coanda effect and Bernoulli's principle to create two distinct air velocity profiles within the intake pipe. This dual-velocity approach optimizes airflow efficiency, delivering up to three times more air to the engine than conventional air intake systems. The intake pipe is crafted from high-quality 6061 aluminum using a CNC mandrel bending process, with a polished finish. The system includes a specially designed air filter with a tuned velocity stack to reduce turbulence and increase air velocity, and a 1-inch thick high-flow polyurethane foam filtering element for exceptional filtration with minimal airflow restriction. The foam element is reusable and easy to clean. The product is backed by a 1 million-mile warranty and features patented technology (US patent #7,263,961B2).

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
