Cobb 02-07 Subaru WRX / 04-07 STi / 04-08 FXT SF Airbox Kit
The Cobb SF Airbox Kit replaces the restrictive factory airbox on your Subaru with a high-volume intake system that delivers more air to the turbo. Designed for 2002-2007 Impreza WRX, 2004-2007 Impreza WRX STI, and 2004-2008 Forester XT models, it reduces intake temperatures and supports higher boost levels for noticeable power gains. This direct bolt-on upgrade works with stock or aftermarket intake setups.
Key Features
- Large Conical Filter: Provides massive surface area for unrestricted airflow, supporting up to 500hp while filtering dirt effectively.
- Smooth Bellmouth Inlet: Directs air efficiently into the turbo with minimal turbulence, improving throttle response and spool time.
- Sealed Heat Shield: Blocks engine bay heat to maintain cooler intake air temperatures, preventing power loss from heat soak.
- High-Temp Polymer Construction: Withstands extreme underhood conditions without cracking or warping over time.
- Factory-Like Fit: Bolts directly to OEM mounting points, retains stock MAF sensor placement for seamless tuning compatibility.
Product Notes
- Reuses OEM air inlet tube or pairs with Cobb 3" intake for full system gains.
- Clean filter every 15,000 miles or sooner in dusty conditions for peak performance.
Installation Notes
- Professional installation recommended.
- Complete install takes 30-45 minutes with basic hand tools no cutting or modifications needed.
- Includes all necessary hardware and reuses factory MAF harness and couplers.
