Product Description

The Weapon-R 307-158-101 Secret Weapon intake is a vehicle-specific performance air intake designed for a broad range of Buick, Chevrolet, Oldsmobile, and Pontiac applications using the listed V6 and V8 engines. The system uses polished 6061 aluminum intake tubing and Weapon-R's Secret Weapon filter technology to provide a less restrictive airflow path while adding a performance-oriented appearance and intake sound.

Its SW1 filter incorporates a tuned velocity stack designed to increase airflow velocity and reduce turbulence before air reaches the engine. The intake is offered as an application-specific system rather than a universal intake, so the exact vehicle year, engine, and configuration should be matched against the fitment list before installation.

The 307-158-101 is intended for enthusiasts upgrading the factory intake system on the specified GM platforms. Installation is designed around the listed vehicle applications, with the intake, filter, hardware, and installation instructions supplied as part of the system.
