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