SF Intake Black and Airbox

The COBB Tuning SF Intake Black and Airbox is a comprehensive intake system replacement engineered for the 2008-2014 Subaru WRX and WRX STI models. This package integrates the Cobb SF Intake System with the Cobb SF Airbox, providing an enclosed cold-air path to enhance airflow performance while mitigating heat soak. The SF Airbox is crucial for thermal management, addressing the common issue of open cone filters drawing in hot engine bay air, especially during extended driving or track use. By enclosing the cone filter within a sealed structure that utilizes an external cold-air inlet, the SF Airbox maintains lower intake air temperatures compared to open-element filters. This combination ensures better thermal isolation and improved airflow capacity. The included calibration accounts for the unique airflow characteristics of this integrated intake system, ensuring optimal performance and correct air mass measurement as the MAF sensor position is maintained. All necessary hardware and couplers for a complete installation are provided. Cobb Tuning, founded in 1999, has a long-standing reputation for developing performance software and hardware for turbocharged enthusiast vehicles. Their integrated approach ensures that hardware products are validated as part of a complete system, leading to consistent and reliable results. The SF Black Intake + Airbox is recommended for builds that prioritize both performance gains and effective thermal management.
