Features: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 BRZ/86 Post MAF Hoses are comprised of 4-ply silicone and unlike their competitor's offerings, are reinforced with an internal stainless steel wire running the length of each piece. This makes Grimmspeed 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 throttle body. A mis-matched diameter creates steps, which will interrupt the air flow trajectories and create small vortexes in the post MAF hoses. Grimmspeed variants are designed specifically to prevent these issues.

Need to dyno the car to see but seems I lost a bit of power when paired with the Perrin intake and remark axle back exhaust. Will dyno in a few weeks and check. But easy install and make engine bay look great. 5 starts if I had power increases
Easy installed. I immediately noticed how smooth the ride feel and gained mpg, it went from 27.2 to 28.2
