Perrin Performance Afta-Maf Tube Black Subaru 2008-2014 WRX / 2008-2020 STI

Simple to install and easy to appreciate, the AFTA-MAF is an eloquent compliment to every engine bay. Replaces the factory corrugated rubber hose between the inlet tube and air box. By removing the pleats found in the OEM hose, the increased air flow makes more horsepower, decreases turbo spool time, and improves acceleration.
