GrimmSpeed Post MAF Hose Kit Black Subaru WRX 2015-2022

The GrimmSpeed 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, reinforced with an internal stainless steel wire running the length of each piece. This makes the hoses sufficiently flexible and also allows them to retain strong structural properties for a design that maximizes flow, is very easy to install, and won't collapse under vacuum. The second feature are tapered end portions, making sure the inner diameter matches the OEM air box and turbo inlet. A mismatched diameter creates steps, which will interrupt the airflow trajectories and create small vortexes in the post MAF hoses. GrimmSpeed variants are designed specifically to prevent these issues.
