Product Description

The Weapon-R 304-140-101 Secret Weapon Intake is an aftermarket performance short-ram intake system engineered for *2009-2015 Nissan 370Z* and *2008-2013 Infiniti G37* models equipped with the 3.7 L V6 and twin throttle body setup. This intake replaces the restrictive stock air box and tubing with a CNC mandrel-bent aluminum tube and a high-flow SW1 reusable foam air filter with a tuned velocity stack, designed to deliver smoother, higher-velocity airflow into the engine.

By creating dual airflow velocity profiles, the Secret Weapon design aims to increase air volume and speed entering the engine compared to standard intake systems, which can improve throttle response and engine sound. Installation is straightforward with a direct bolt-on design that uses included hardware and requires only basic tools. The polished finish enhances under-hood aesthetics, and the reusable filter element provides long-term performance. With Weapon-R's 1 Million Mile Limited Warranty, this intake offers both performance and reliability for Nissan and Infiniti enthusiasts.
