SUBARU AIRBOX STI 2015-2018

The COBB SF Air Box enhances the already impressive performance of the COBB SF Intake by adding the benefits of a cold air intake system. By enclosing the SF Intake and directing fresh air from the factory grill inlet, the air box ensures that only cool, dense air reaches your engine. This helps prevent heat soak from hot under-hood air, delivering consistent intake performance and improved power potential.

Designed with practicality in mind, the SF Air Box also prevents water ingestion issues commonly seen with traditional in-fender cold air intakes. A directional lid and thoughtful design separate rainwater from the intake air, ensuring safe and reliable operation in all conditions.

Constructed from 16-gauge aluminum, the COBB SF Air Box features a one-piece surround for durability, a directional lid for optimized airflow, and stainless steel hardware for long-term reliability. Installation is simple and seamless, with OEM-quality fit and finish that integrates cleanly into your engine bay.
