OVERVIEW

The PERRIN Adjustable Fuel Pressure Regulator is designed with adjustability and high-flow fuel regulation in mind that works with fuel systems ranging from stock setups to 1000+ horsepower setups and is the best option to fix the stumbling issue present in 2008+ STIs.

HIGH-FLOW

Of the (6) -6 ports on the Adjustable Fuel Pressure Regulator, (4) of these ports are used to connect to your fuel rails with maximum flow in mind. Rated to 1,000+ horsepower worth of fuel flow, this kit works perfectly with stock engines.

REPLACES OEM REGULATOR

The PERRIN Adjustable Fuel Pressure Regulator replaces the cumbersome and overly complicated OEM fuel pressure regulator on your 2008-2018 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.

ADJUSTABILITY

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.

MAXIMUM FLOW

There are (6) -6 ports on the Adjustable Fuel Pressure Regulator: (1) for fuel pump feed, (2) for fuel rail feed, (2) for fuel rail return, and (1) for fuel tank return. This allows for the easy installation of aftermarket fuel rail kits that utilize more than one rail.

DIRECT BOLT-ON

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.

CONSTRUCTION

Internal components protected under Patent # 6,298,828. These components are licensed to PERRIN Performance for the technology related to the Adjustable Fuel Pressure Regulator's features. Using this proven technology ensures internal components will last the duration of your vehicle's life.

FINISH

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 labeled according to their proper connections.

NO TUNING REQUIRED


Increase horsepower and torque without ECU recalibration or tune! This part is designed and tested to work safely on your vehicle without any tuning required! However, more power can be gained with proper ECU tuning!
