Product Description
Some OE parts look passable and others miss the mark. In the case of the factory post MAF hose, the quicker you can get it out of your bay, the better. GrimmSpeed now has you covered with our all new Post MAF Hose Kit which not only looks better, but fixes the performance flaws of its OE counterpart.
Our Post MAF Hose construction improves flow with 2 main features:
The first is the smooth inner surface, removing the pockets from the OE structural corrugated folds. The GrimmSpeed Hose is made with reinforced silicone, which is flexible, but has strong structural properties that allow for a design that maximizes flow, is very easy to install and won't collapse 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.
