Cobb Subaru Airbox - 2015-2018 Subaru STI
The COBB SF Airbox adds the benefits of a cold air intake to the proven performance of the COBB SF Intake. By using the factory inlet/snorkel to direct cool air from the front grille into an enclosed airbox, this setup helps keep hot engine bay air out of the intake path for more consistent performance.
Unlike many in-fender cold air intakes, the COBB SF Airbox is also designed to help separate rainwater from the intake air, reducing the water ingestion concerns that can come with other intake layouts. The result is a cleaner, more OEM-like solution that supports performance without sacrificing practicality.
Key Features
- Cold Air Intake Benefits: Helps feed cooler air to the intake system for more consistent performance.
- Uses Factory Snorkel: Takes advantage of the OEM inlet path to direct fresh air into the airbox.
- Helps Block Engine Bay Heat: Enclosed design reduces exposure to hot under-hood air.
- Water Management Advantage: Designed to separate rainwater from intake air, unlike many in-fender CAI setups.
- 16 Gauge Aluminum Construction: Durable aluminum build for strength and long-term use.
- OEM-Quality Fit and Finish: One-piece surround and directional lid for a clean, integrated install.
- Easy Installation: Includes the necessary components for a straightforward installation.
