In the case of the factory post MAF hose, the quicker you can get it out of your bay, the better. We’ve now got you covered with The GrimmSpeed Post MAF Hose Kit that not only looks better, but fixes the flaws of its OE counter part. Our hose construction improves flow with 2 main features: The first is the smooth inner surface, removing the pockets from the OE corrugated folds. These folds are necessary for the factory rubber design for flexibility during installation and structural integrity. The Grimmspeed hose is made with reinforced silicone, which is flexible, but has strong structural properties that enable us to have a hose that is very easy to install without worrying about collapsing under vacuum. The second feature is a tapered center portion, 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 hose. The Grimmspeed hose was designed specifically to prevent these issues: Testing The first step in improving on an existing part is to find its shortcomings. The OEM rubber hose, designed with the corrugated folds, requires a straight section in the middle, which means sharper curves on both ends. This contributes to uneven air flow through the hose with high and low pressure spots. The GrimmSpeed hose design can support a minimal curve transition, maximizing air flow. The plot below shows the pressure through the length of the hose, the GrimmSpeed design resulting in a smoother transition from the air box into the turbo inlet:The removal of the corrugated folds also adds a significant reduction in vorticity (a calculation used for flow disruption, with blue representing consistent flow and red more turbulent) between the two designs. Smoother flow will give us a more consistent air supply to the turbo:The tapered center portion is also an important design choice for contributing to even flow through the hose. A plot comparison showing vorticity between a non-tapered version and Grimmspeed’s tapered hose shows an additional reduction in turbulence through the center of the hose where a majority of air flow will occur: Payment: Payment Method: We accept payment thru Paypal only.
