GrimmSpeed MAF Hose Kits | 2015-2021 Subaru WRX (125023.1/2)

2015-2021 Subaru WRX MAF Hose Kits by GrimmSpeed

Part of our job is identifying OE Subaru parts that could be improved upon and creating the best aftermarket versions of them. The pieces that make up your factory intake are a great example. In order for you to maximize both the performance and look of your OEM intake system, we're proud to introduce GrimmSpeed Post MAF Hose Kits for the 2015-2021 Subaru WRX. Coupled with a GrimmSpeed DRY-CON Panel Air Filter, these kits allow your WRX to perform at its best until you're ready for a full aftermarket intake and protune. 

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 a vacuum. 

The second feature is 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. Our variants are designed to specifically prevent those issues.
