Perrin Post MAF Hose Red 2002-2007 WRX / 2004-2007 STI

The PERRIN Performance Afta MAF Hose replaces the factory corrugated rubber hose between the inlet tube and air box with a shiny silicone tube. This is an awesome part for restoring a high mileage or older turbo Subaru that very likely has developed cracks or holes in the original part.

The PERRIN After-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 spool time, and improves acceleration. 

Included:

(1) PERRIN Afta-MAF Intake Tube
(2) Clamps
