GrimmSpeed POST MAF HOSE KIT black for 2015-2021 Subaru WRX (125023.1) 31015 regardless of applicationOur post MAF hose construction improves on OE with 2 main features: First is the smooth inner surface, removing the pockets from the OE structural corrugated folds. The GrimmSpeed Post MAF Hoses are comprised of 4 ply silicone and unlike our competitor's offerings, are reinforced with an internal stainless steel wire running the length of each piece. This makes our hoses sufficiently flexible and also allows them to retain strong structural properties
