PERRIN Afta-MAF Intake Tube, Black (2008-2017 Impreza WRX STi)

SMOOTHER AIRFLOW
The PERRIN Afta-MAF Intake Tube is perfectly smooth on the inside and has a significantly larger internal diameter than the OEM part. The increased air flow by removing the pleats found in the OEM hose makes more horsepower, decreases turbo spool time, and improves acceleration.

DIRECT REPLACEMENT
The PERRIN Afta-MAF Intake Tube replaces the factory corrugated rubber hose between the inlet tube and air box. This is an awesome part for restoring a high mileage or older WRX, STI, or Legacy GT. These older parts can become hard and brittle, and may very likely develop cracks or holes in the original part. Available in red or black silicone.
