Grimmspeed Post MAF Hose Kit RED- Subaru 15-21 WRX - 125023.2 44mm AEM's wideband UEGO air/fuel ratioOur 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
