Perrin Blow-Thru Boost Tube Subaru WRX/STI 02-07

Front Mount Intercooler users can now get a 100% accurate airflow temperature reading. Instead of measuring air temperature and volume before the turbo, the PERRIN PerformanceTM Blow Through Intercooler Hose moves the mass airflow sensor so that readings are taken just before the throttle body. Allows for proper use of a vent to atmosphere Blow Off Valve (part #PSP-INT-620).

Use with Front Mount Intercooler P/N PSP-ENG-400.
