IAG Performance PTFE Fuel System Kit with ID 1050cc Injectors, Aeromotive FPR, Red IAG Fuel Rails – 2008-2014 Subaru WRX / 2008-2021 STI

IAG PTFE Fuel System Kit — ID 1050cc Injectors / Aeromotive FPR / Red IAG Fuel Rails — 2008-2014 WRX / 2008-2021 STI

Complete Fuel System in One Package
The IAG PTFE Fuel System Kit with ID 1050cc Injectors combines IAG’s PTFE fuel lines, Red IAG Top Feed Fuel Rails, an Aeromotive fuel pressure regulator, IAG fuel pressure gauge, and 90-degree gauge adapter into a single package. Everything needed for a complete high-flow fuel system installation is included — no sourcing individual components or verifying compatibility. Made in the USA from chemical-resistant PTFE and designed for compatibility with both OEM and IAG TGV housings.

PTFE Fuel Lines — Why They Matter
IAG’s PTFE fuel lines use Fragola 6000 series PTFE hose with stainless steel reinforcement and a black nylon outer covering to prevent scratching. The lines are pre-assembled to application-specific lengths for a direct installation — no cutting or fitting assembly required. Working pressure is 2000 psi (burst 8000 psi). PTFE does not allow permeation of fuel vapors, which eliminates the fuel smell that other hose types can exhibit. The hose is compatible with all automotive fuel types including E85.

Complete Package — No Sourcing Required
High-flow fuel system upgrades typically require sourcing injectors, lines, rails, an FPR, and a pressure gauge separately — each from different suppliers, with compatibility research at every step. IAG’s fuel system kit eliminates that process. Every component is selected to work together and the kit includes everything needed for a direct installation.

TGV Compatibility
The IAG fuel system kits are engineered to work with both OEM and IAG TGV housings, using existing sensors and motors without additional modification. No special TGV work is required beyond having aftermarket TGV housings installed.

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 fuel system kit is the efficient way to build out a complete high-flow fuel system on an 08-21 WRX or STI. The 1050cc injectors, PTFE lines, Aeromotive FPR, and IAG rails are a proven combination for builds targeting 400-700 WHP on E85 or gasoline. Buying the complete kit is more efficient than sourcing individual components.
