Post MAF Hose Kit - Black

• 2004–2008 Subaru | Forester XT
• 2002–2007 Subaru | WRX
• 2004–2007 Subaru | WRX STI

The GrimmSpeed Post MAF Hose Kit (125009, Black) replaces the factory post-MAF hose on the 2002-2007 Subaru WRX, 2004-2007 STI and 2004-2008 Forester XT with a hose that looks better and fixes the flaws of its OE counterpart. GrimmSpeed's construction improves flow with two main features:

• A smooth inner surface that removes the pockets of the OE corrugated folds. The GrimmSpeed hose is made of reinforced silicone, which is flexible yet structurally strong, so it is easy to install without worrying about collapsing under vacuum.
• A tapered center portion so the inner diameter matches the OEM air box and turbo inlet, avoiding steps that interrupt airflow and create small vortexes.

removing the corrugated folds allows a minimal curve transition and a smoother transition from the air box to the turbo inlet, with reduced turbulence for a more consistent air supply to the turbo. Coupled with the GrimmSpeed DRY-CON Panel Air Filter, it is designed to maximize your factory intake system until it is time to upgrade to a full GrimmSpeed intake.
