Cobb 02-07 WRX/STI Black SF Intake
The Cobb Black SF Intake System delivers increased airflow to 2002-2007 Subaru Impreza WRX and 2004-2007 WRX STI engines. This bolt-on upgrade replaces the restrictive factory airbox with a 3.5-inch aluminum tube and oversized filter for immediate power gains up to 15 wheel horsepower. Drivers experience sharper throttle response and a distinctive intake sound on GD-chassis Subarus.
Key Features
- 3.5-Inch Aluminum Intake Tube: Smooth mandrel-bent design supports high boost levels and unrestricted airflow over stock 2.75-inch piping.
- Oversized Conical Air Filter: High-flow media captures contaminants while allowing 99% more air volume than OEM filter for consistent power delivery.
- CNC-Machined MAF Flange: Ensures precise sensor alignment for accurate fueling and no check engine lights on stock or tuned ECUs.
- Black Powder-Coated Components: Corrosion-resistant finish on bracket and hardware withstands engine bay heat and road conditions.
- Silicone Couplings & Stainless Clamps: Secure, flexible connections handle pressure changes without leaks or slippage.
Product Notes
- Filter is reusable clean every 15,000-30,000 miles with proper service kit.
- Works with stock tune or Cobb Accessport for maximum gains.
Installation Notes
- Professional installation recommended.
- 30-60 minute install using basic hand tools no cutting or permanent modifications.
