Subaru Silicone Turbo Inlet V2

The COBB Tuning Subaru Silicone Turbo Inlet V2 is a direct replacement designed to enhance the performance and reliability of your 2008-2021 Subaru STI. Constructed from durable black 6-ply silicone, this inlet hose is reinforced with steel wire to prevent collapse under vacuum, a common issue with lesser quality hoses. Its custom silicone construction effectively rejects high engine bay temperatures, helping to keep intake air closer to ambient temperature. The V2 design incorporates several updates to ease installation and improve fitment. Machined billet aluminum adapters provide a secure connection for the Post-MAF hose and BPV return, while a plug-and-play adapter ensures OEM-level integration for the PCV connection. Fittings have been redesigned to prevent protrusion into the inlet airway, and the overall tube path has been optimized for improved clearance around TGV Housings. This larger diameter inlet allows for increased potential airflow delivery to the turbo, potentially increasing horsepower, decreasing turbo spool time, and improving throttle response and acceleration. This inlet requires tuning changes to function correctly. COBB Tuning offers Off-The-Shelf (OTS) Map support for compatible vehicles. Please check the available maps for your specific car.
