Perrin Cold Air Intake Red 2002-2007 WRX / 2004-2007 STI | Enhanced Airflow | Performance Intake System
Overview
The Perrin Cold Air Intake is a precision-engineered upgrade designed specifically for the 2002–2007 Subaru WRX and 2004–2007 WRX STI models. This intake system improves engine breathing by maximizing airflow and reducing intake restrictions, resulting in noticeable horsepower and torque gains. It also enhances throttle response and delivers a deep, aggressive intake sound that adds to the driving experience without compromising daily drivability.
Built with durable aluminum tubing and finished in a vibrant red powder coat, the Perrin intake combines robust construction with a clean, aggressive aesthetic under the hood. Unlike generic universal intakes, this system is tuned for Subaru’s factory ECU to maintain smooth air-fuel ratios and OEM-level drivability, minimizing the need for immediate tuning after installation.
For Subaru enthusiasts seeking a reliable, bolt-on performance upgrade, this intake offers a balance of power gains, sound enhancement, and long-term durability. The reusable high-flow foam filter extends service intervals while protecting the engine from contaminants, making it an ideal choice for both street and occasional track use.
