The factory configuration is limited in the amount of power it can support on the Subaru side-feed fuel injector design and it does not benefit from having as many bolt-in aftermarket injector options. The COBB Side Feed to Top Feed Fuel Rail Conversion Kit allows a top-feed style fuel injector to be bolted into place without having to change out the Tumble Generator Valve assemblies. This opens up injector upgrade options!
