IAG provides a simple fuel rail solution that lowers the conversion cost to top feed injectors on older STI’s, Foresters XT's and Legacy GT’s. The conversion kit allows you to keep your side feed TGV’s in place, simply swap in our injector conversion bosses, new conversion rails, hardware and your choice of top feed injectors*.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eThe IAG Performance Side Feed to Top Feed Fuel Rail Conversion Kit is designed to increase the power ceiling on your Subaru's fuel system. The factory fuel rails function in a series, which means that each cylinder's fuel is delivered after the other. As horsepower rises past the 350whp mark, the stock rail often does not have the capacity to deliver fuel to the last cylinder effectively. As a result, that last cylinder can run lean, which can result in catastrophic failure. The IAG billet fuel rails are designed to eliminate this problem.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eFirst, our fuel rails operate in parallel format, each cylinder bank receives equal fuel, matching the flow between the rails ensure 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. These fuel rails were real-world tested to 850hp. The fuel rails also feature a port to add an optional fuel 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 rails locate the damper between the injectors to smooth out the fuel flow.\u003c\/p\u003e\n\u003cp align=\"justify\"\u003eThe fuel rails are engineered and manufactured at the IAG facility in Westminster, Maryland. The rails are machined from a solid block of 6061 billet aluminum and feature an anodized finish with the IAG laser marked logo on the top.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eMachined from a solid block of 6061 billet aluminum with an anodized finish and the IAG engraved logo\u003c\/li\u003e\n\u003cli\u003eDesigned to increase the power ceiling on your Subaru's fuel system\u003c\/li\u003e\n\u003cli\u003eOperate in parallel format, each cylinder bank receives equal fuel\u003c\/li\u003e\n\u003cli\u003eBore is machined to 5\/8\" ID and is designed to accept -8 O-ring boss fittings\u003c\/li\u003e\n\u003cli\u003eGreatly increases volume, meaning that more fuel is available at higher power levels\u003c\/li\u003e\n\u003cli\u003eThese fuel rails were real world tested to 850hp\u003c\/li\u003e\n\u003cli\u003eIncludes a port to add an optional fuel damper between each pair of injectors\u003c\/li\u003e\n\u003cli\u003eDampers absorb fuel oscillations caused by injectors opening and closing\u003c\/li\u003e\n\u003cli\u003eEngineered and manufactured at the IAG facility in Westminster, Maryland\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003ePlease Note\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eNot compatible with Injector Dynamics ID2000cc injectors without switching out the billet top hat.\u003c\/li\u003e\n\u003cli\u003eThis kit does not include fuel lines, but they are available separately.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv id=\"newdescrLC\"\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e2004 - 2006 Subaru STI\u003c\/li\u003e\n\u003cli\u003e2005 - 2007 Subaru Legacy GT\u003c\/li\u003e\n\u003cli\u003e2004 - 2005 Subaru Forester XT\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eConfirmed Injector Fitment\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eInjector Dynamics 1050x\u003c\/li\u003e\n\u003cli\u003eInjector Dynamics 1300x\u003c\/li\u003e\n\u003cli\u003eInjector Dynamics 1700x\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhat's In The Box?\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e2 - Billet fuel rails\u003c\/li\u003e\n\u003cli\u003e2 - Plugs\u003c\/li\u003e\n\u003cli\u003e4 - Side feed to top feed injector conversion bosses\u003c\/li\u003e\n\u003cli\u003e4 - Bolts\u003c\/li\u003e\n\u003cli\u003e4 - Phenolic spacers\u003c\/li\u003e\n\u003cli\u003e4 - Injector O-Rings\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eReferences\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/www.iagperformance.com\/v\/vspfiles\/downloadables\/instructions\/IAG\/IAG-AFD-2131\/IAG-AFD-2131-Fuel-Rail-Tech-Sheet.pdf\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eInstallation Instructions\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWarranty\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eManufacturer Standard Warranty\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"clear\"\u003e\u003c\/div\u003e","brand":"IAG Performance","offers":[{"title":"Black","offer_id":30288728129606,"sku":"IAG IAG-AFD-2132BK","price":219.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0890\/6136\/products\/iag-performance-iag-iag-afd-2132bk-black-12809406808134.jpg?v=1756999664","url":"https:\/\/www.maperformance.com\/products\/iag-side-to-top-feed-fuel-rail-conversion-kit-04-06-subaru-sti-05-07-lgt-04-05-fxt-iag-afd-2131","provider":"MAPerformance","version":"1.0","type":"link"}
