The PERRIN Subaru STI 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 the best option to fix the stumbling issue present in Subaru STIs.

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 as well as heavily modified engines thanks to the interchangeable orifices.

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