IAG Fuel Pressure Regulator Adapter — 2002-2007 Subaru WRX / 2007 STI

The IAG Fuel Pressure Regulator Adapter for 2002-2007 WRX and 2007 STI is machined from a single piece of 6061 aluminum and designed to allow the stock FPR to be remote-mounted. It retains the stock fuel line outlet, converts the O-ring inlet to a 3/8″ OD hose barb, and includes a 1/4″ mounting hole for universal engine bay mounting with a single 6mm bolt.

Why Remote Mount the FPR?
Remote mounting the FPR is sometimes necessary when installing aftermarket components in the engine bay that conflict with the stock FPR location. These adapters allow the FPR to be relocated to a convenient mounting point while retaining the stock fuel line connections.

Machined Aluminum Construction
IAG’s FPR adapters are machined from 6061 aluminum — the same material used across IAG’s fuel system components. This ensures compatibility with all fuel types including E85 and provides long-term corrosion resistance.

Hardware Included
Each adapter includes the appropriate mounting hardware for installation. The Viton O-ring (where applicable) ensures a leak-free seal at the OEM fuel rail interface.

Why Choose IAG Performance

IAG Performance has been building Subaru-specific engine and drivetrain components since 2001, and in that time they have become the standard by which serious Subaru builds are measured. Based in Westminster, Maryland, IAG designs, machines, and assembles their products in-house using Haas CNC equipment and their own engineering team. Their catalog spans everything from short blocks and long blocks rated to 1150 BHP all the way down to the fuel system, oiling, and drivetrain hardware that keeps modified Subarus running reliably for years. Every IAG product exists because a problem needed a better solution than what was available — and the engineering shows.

The RallySport Take

The IAG FPR adapter is a small but important piece when reconfiguring the fuel system on a 2002-2007 WRX / 2007 STI. Machined from aluminum, correct O-ring included, and designed to work with common aftermarket FPR specifications.
