GrimmSpeed Silicone MAF Hose, 2015-2021 WRX

Our 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 for a design that maximizes flow, is very easy to install and won't collapse under vacuum.
The second feature is tapered end portions, making sure the inner diameter matches the OEM air box and turbo inlet. A miss-matched diameter creates steps, which will interrupt the air flow trajectories and create small vortexes in the post MAF hoses. Our variants are designed specifically to prevent these issues.
