Perrin Performance Adjustable Fuel Pressure Regulator - Subaru Impreza WRX STi 2008-2015

Perrin Adjustable Fuel Pressure Regulator - Subaru Impreza WRX STi 2008-2015

The PERRIN Adjustable Fuel Pressure Regulator replaces the cumbersome and overly-complicated OEM fuel pressure regulator on your 2008-2015 STI. Removing the OEM part along with the two fuel pressure dampeners significantly reduces the common complaint from STI owners that their car stumbles around 3,000 rpm. After years of development, a design was settled upon that works for applications ranging from stock to heavily modified.

The PERRIN Adjustable Fuel Pressure Regulator can be adjusted from 20 psi to maximum fuel pump capacity. This allows for added fuel delivery to your engine without recalibrating your ECU. Included are three interchangeable orifices for stock fuel pumps, larger drop-in pumps, and fuel systems supporting 1,000+ horsepower.

The PERRIN Adjustable Fuel Pressure Regulator is easy to install as it bolts right into the existing threads where the OEM fuel pressure regulator assembly is normally housed. Installation of this kit requires no special tools.

The PERRIN Adjustable Fuel Pressure Regulator comes with a black anodized finish to make certain your part continues to look good and resist corrosion during its use. For your convenience the ports are labelled according to their proper connections.
