Blow-thru Boost Tube w/BigMAF

PERRIN Front Mount Intercooler users can now get a more accurate charge temperature reading and run a VTA BOV with no problems! Instead of measuring the Mass Air Flow (MAF) and air temperature before the turbocharger, the PERRIN PerformanceTM Blow-Thru boost tube moves the mass airflow sensor to the boost tube before the throttle body. The placement of this does many good things like allowing your ECU to read the actual charge temp the engine sees, which eliminates any need for a Cold air intake (MORE IN FEATURES). Also use our Vent to Atmosphere (VTA) Blow off valve with out running rich between shifts, or with out idle problems. (see ASM-INT-600)

The Blow-Thru boost tube also is designed with the BigMAF Intake in mind. Tuners around the world are familiar with this larger than stock MAF housing. This allows for the stock ECU to read more air flow, in turn allowing the tuner to tune beyond 550WHP! This also means the Blow-Thru boost tube needs to be tuned after installed. This part will not function correctly when installed on a stock tuned ECU.
