Cold Air Intake for Subaru WRX (2002-2007) 2.0L 2.5L Turbocharged Engine

Maximize Turbo Efficiency and Boxer Rumble for the Subaru EJ-Series

Who It’s For: Designed specifically for 2002-2007 Subaru Impreza WRX and STI owners running the legendary EJ-Series turbocharged engine. Whether you’re piloting a Bugeye, Blobeye, or Hawkeye, this is for the enthusiast who wants to hear their turbo work and feel the improved throttle response.

The Problem: The EJ-Series engine is a masterpiece of rally heritage, but the factory airbox is a major bottleneck. The stock plastic piping and baffled box are designed more for silence than for flow, creating significant intake restriction. This mutes the iconic turbo spool and limits the volume of air available to the compressor during high-RPM pulls, especially on modified cars running higher-than-stock boost.

The Solution: We engineered this performance intake to replace the restrictive factory assembly with a high-flow, 2-piece polished aluminum system. By smoothing the intake tract and utilizing a high-velocity cone filter, we’ve minimized turbulence and maximized air volume to the turbo inlet. This kit corrects the factory design flaws of the EJ-Series intake path, delivering reliable performance and that signature induction "whoosh" every Subaru enthusiast craves.

Why This is the Ultimate Upgrade

• Increased Airflow Velocity: By removing the baffled factory box, this system allows for a claimed gain of up to 20 HP and 20 lb-ft of torque by reducing the vacuum load on the turbocharger.
• Rugged Aluminum Construction: The 2-piece polished aluminum piping is built to withstand the high under-hood temperatures common in the GD chassis, resisting the heat soak that degrades performance in plastic components.
• Modular 2-Piece Design: Engineered for a precise fitment within the tight confines of the WRX engine bay, making installation straightforward with basic hand tools while ensuring optimal filter placement.
