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 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 are tapered end portions, making sure the inner diameter matches the OEM air box and turbo inlet. A mis-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.

Hello I have the blox racing turbo inlet on the way here (not installed yet). I'm wanting to know if use this part the blox racing turbo inlet looks as if so long I would not need the lower part or if it's to install in air intake would have to cut it to fit the blox racing turbo inlet?
