DETAILS

The factory post-MAF hose on your Subaru works, but it’s restrictive and prone to disrupting airflow. The GrimmSpeed Post-MAF Hose Kit fixes these shortcomings while adding an OEM+ look to your engine bay. Designed with performance and precision in mind, this hose improves airflow and turbo response without requiring a full intake upgrade.

Features:

  • Smooth Inner Surface: Eliminates restrictive corrugated folds of the OEM hose, reducing airflow turbulence while maintaining flexibility.
  • Tapered Center Section: Matches the OEM airbox and turbo inlet diameters to prevent vortex formation and ensure seamless airflow.
  • 4-Ply Reinforced Silicone: Durable, flexible, and heat resistant; available in red or black.
  • OEM Fitment: Direct replacement, no modifications or tuning required.
  • High-Quality Clamps Included: Comes with BREEZE stainless steel hose clamps for a secure, leak-free installation.

Performance Benefits:

  • Smoother airflow reduces high- and low-pressure spots.

  • Lower vorticity for a consistent air supply to the turbo.

  • Improves factory intake efficiency until you upgrade to a full GrimmSpeed Intake.

FITMENT:

  • 2002-2007 Subaru WRX
  • 2004-2007 Subaru STI
  • 2004-2008 Subaru Forester XT
