Product Description

The Weapon R 304-131-302 Secret Weapon Cold Air Intake is a performance intake system developed for the 2003-2006 Infiniti G35 with the 3.5L V6 engine. The 3.5-inch performance configuration is designed to increase the amount and velocity of air entering the engine while providing a dedicated cold-air routing arrangement for the G35.

The system uses 6061 aluminum intake tubing manufactured with CNC mandrel-bending equipment and finished in polished aluminum. Its SW1 filter incorporates a tuned velocity-stack design intended to improve airflow velocity and reduce turbulence. The reusable high-density open-pore foam filter provides a serviceable filtration solution for performance applications.

Fitment includes rear-wheel-drive G35 Base models from 2003-2006 and all-wheel-drive G35 X models from 2004-2006. The X AWD model was not offered for 2003, so it is listed separately. Verify the vehicle's exact MAF configuration and intake routing before installation to ensure compatibility.
