This is the IAG Performance Side Feed To Top Feed Fuel Rail Conversion Kit. This kit is for previous-generation Subaru models that came from the factory with side-feed injectors that want to convert to a higher-flowing and more efficient top-feed fuel system without having to convert to top-feed style TGV's. With the IAG Top Feed Fuel Rail Conversion Kit, you will allow for a larger selection in fuel injector sizes so that you can raise the power limits of your build.
