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.
Increase horsepower and torque without ECU recalibration or tune! This part is designed and tested to work safely on your vehicle without any tuning required! However, more power can be gained with proper ECU tuning! Confirm any tune or recalibration you add is specific for ALL modifications added to the vehicle. Questions? Contact [email protected].
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.
