Perrin Post MAF Hose Black 2008-2014 WRX / 2008-2021 STI / 2005-2009 Legacy GT
The PERRIN Performance Afta MAF Hose replaces the factory corrugated rubber hose between the inlet tube and air box with a shinny black, red or blue silicone tube. This is an awesome part for restoring a high mileage or older turbo Subaru that very likely has developed cracks or holes in the original part.
