Features & Product Details
RallySport Direct proudly carries a great selection of quality aftermarket performance products brought to you by GrimmSpeed.
This is the GrimmSpeed Post MAF Hose Kit. This post-MAF hose combines durable multi-layer silicone fiber and smooth interior walls and CAD technology that makes for an excellent high-performance upgrade over the factory OEM post-MAF hose. This is achieved by eliminating the pockets and corrugated folds in the OEM design to improve the overall flow and throttle response.
