Perrin [08-14 WRX, 08-21 STI, 05-09 LGT] Post MAF Hose Black | PSP-INT-355

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.
