Create smooth and even airflow while adding style under your hood with the PERRIN Afta-MAF Intake Tube.

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. By removing the pleats found in the OEM hose, the increased air flow 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.

5 Year Warranty

PERRIN Performance warrants to the original purchaser that all PERRIN products will be free from defects in material and workmanship within a sixty (60) month period from the date of purchase. *Some exclusions apply
