SF Intake System with Airbox

The COBB Tuning SF Intake Black and Airbox is a comprehensive intake system replacement engineered for 2008-2014 Subaru WRX and WRX STI vehicles equipped with the EJ255 MT or EJ257 MT engines, respectively. This package combines the SF Intake System with the SF Airbox, offering an improved airflow path for enhanced performance. The SF Intake features a high-flow cone filter paired with a durable aluminum tube and a black coupler. This design mitigates heat soak, a common issue with open-cone filters, especially during extended driving or track use, thereby ensuring more consistent intake air temperatures and better thermal management. This integrated system is specifically calibrated to work with COBB's Accessport SF intake OTS (Off-The-Shelf) maps. The MAF sensor position is maintained to ensure correct air mass measurements, crucial for optimal engine performance. The kit includes all necessary hardware and couplers for a complete installation. COBB Tuning, established in 1999, is known for developing performance software and hardware for turbocharged enthusiast vehicles.
