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.

TECHNICAL:

Reinforced silicone construction

The design removes the OEM corrugated folds and the pockets to create a smooth interior wall

Designed with a tapered center portion to make sure the diameter matches the OEM air box and turbo inlet

The design eliminates mismatched hose diameter which can create steps that will cause airflow trajectories and small vortexes

The shape of the hose was optimized through CAD Flow Simulation Testing to generate a smoother flow path

The removal of the corrugated folds adds a significant reduction in vorticity to calculate the highest flow efficiency

The tapered center portion in the design has an emphasis on vorticity to reduce as much turbulence as possible

DETAILS:

Black finish

4-ply reinforced silicone hose construction

CAD-optimized center section to match airbox and inlet for seamless flow

GrimmSpeed logo stamped on the airbox side of the hose

Includes Breeze hose clamps for the installation

I can't talk about performance of this thing, but Grimmspeed says it flows smoother than the stock hose. Install took two minutes of wrestling it off the Tomei turbo inlet I have and sliding it back on. Got it in black to match the stock look of the 05 STI I have. Expensive for a simple hose, though. That's my only qualm.
