GrimmSpeed Post MAF Hose Kit Black
Subaru WRX / STI 2002-2007
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.

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.
