IAG Top Feed Conversion Kit - V2 Silver TGV Black Fuel Rails Custom Lines For OEM FPR (04-06 STI 04-05 FXT).

The IAG Performance Top Feed Conversion Kit is designed to completely convert the 2004-06 Subaru STI and 2004-05 Forester XT from side feed TGV/Rails/Lines to top feed TGV/Rails/Lines. This is not just a fuel rail conversion kit, it includes the IAG V2 CNC billet aluminum top feed TGVs, IAG V3 top feed fuel rails, lower TGV gaskets, and braided fuel hose and fuel fittings that are designed for applications retaining the OEM FPR (Fuel Pressure Regulator). Top feed injectors (sold separately) are required for use with this kit. IAG recommends Injector Dynamics fuel injectors. This kit features Silver TGV housings and Black Fuel Rails. The IAG V3 fuel rails also feature a port to add an optional fuel pressure pulsation damper between each pair of injectors. Fuel dampers absorb fuel oscillations caused by injectors opening and closing. All Subaru's are equipped with a fuel damper however its location is some distance from the injectors. The IAG V3 rails locate the damper between the injectors to help maintain constant pressure. First, our fuel rails operate in parallel format, each cylinder bank receives equal fuel, matching the flow between the rails ensures that each injector sees the same fuel pressure. Second, the bore of our rail is machined to 5/8" ID and is designed to accept -8 O-ring boss fittings. This configuration greatly increases the volume of the rail which means that more fuel is available at higher power levels and IAG's fuel rails were real-world tested to 1000 hp. Finally, the IAG V3 fuel rails add phenolic spacers that are located between the rails and the TGV's. The phenolic spacers aid in reducing heat transferring from the engine to the fuel entering the engine.
