Product Description

The Weapon‑R 301‑148‑101 Secret Weapon Intake is a performance short‑ram air intake system designed for the 2004–2008 Acura TSX 2.4L I4 engine. This intake replaces the factory air box and restrictive tubing with a CNC mandrel‑bent aluminum tube that improves airflow and throttle response. The SW1 high‑density foam filter with a tuned velocity stack increases air velocity and volume, helping the engine breathe more efficiently while enhancing performance and engine sound.

Installation is straightforward with a direct bolt‑on design requiring basic hand tools. The reusable filter allows for easy maintenance, and the polished aluminum finish provides a clean, performance‑oriented look under the hood. This system is engineered for enthusiasts seeking improved airflow, throttle response, and under‑hood aesthetics, while maintaining reliability and long-term durability.
