Weapon R 99-02 Toyota 4Runner 3.4L Secret Weapon Intake

The Weapon-R Secret Weapon Intake is designed to significantly increase engine air intake volume and speed, claiming up to three times more airflow than conventional systems. This is achieved through a patented technology that creates two distinct air velocity profiles. The intake pipe is constructed from high-quality 6061 aluminum, precisely bent on a CNC mandrel bender, and polished for a show-quality finish. It includes a Secret Weapon Air Filter featuring a tuned velocity stack to optimize airflow and minimize turbulence. This is a direct bolt-on system, dyno-tested to enhance acceleration and engine sound while increasing horsepower. The air filter is a reusable, open-pore, high-density foam type. The product comes in a polished finish only and is backed by a 1 Million Mile Limited Warranty. It does not have a CARB EO # and is not legal for sale in California.
