About This Item

The PERRIN Adjustable Fuel Pressure Regulator is the ideal solution to address the stumbling issue present in STIs manufactured in 2008 and later. It was developed with flexibility and high-flow fuel control in mind.

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. Of the 6-ports on the Adjustable Fuel Pressure Regulator, four 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. 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.

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. There are 6-ports on the Adjustable Fuel Pressure Regulator: (1) for fuel pump need, (2) for fuel rail need, (2) for fuel rail return, and (1) for fuel tank return, this allows for easy installation of aftermarket fuel rail kits that utilize more than one rail. 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. Unlike competitors' fuel pressure regulators, the PERRIN Adjustable Fuel Pressure Regulator has a port located discretely on the bottom of its assembly. This 1/8th NPT threaded port allows for the installation of aftermarket fuel pressure sensors and/or gauges.

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. 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.
