Overview
The Perrin Post MAF Hose is a direct replacement intake hose designed to improve airflow and engine response on select Subaru turbo models, including the 2008-2014 WRX, 2008-2021 WRX STI, 2005-2009 Legacy GT, and 2005-2009 Outback XT.

Engineered with a smooth interior and a larger diameter than the OEM hose, the Perrin Post MAF Hose eliminates the pleats found in stock hoses that can disrupt airflow.

By upgrading to this silicone hose, Subaru owners benefit from a more consistent and unrestricted airflow path, which supports better combustion and power delivery.
