COBB Side Feed To Top Feed Fuel Rail Conversion Kit 2004-2006 STI / 2004-2005 Forester XT / 2005-2007 Legacy GT

Unlock greater fueling potential with the COBB Side Feed to Top Feed Fuel Rail Conversion Kit, designed for Subaru models equipped with factory side-feed injectors. Machined from 6061 billet aluminum and finished in sleek black anodizing with a laser-etched COBB logo, these rails are engineered for both performance and durability.

Each rail includes pre-installed -8AN to -6AN adapters, enabling seamless plug-and-play integration with standard -6AN fuel lines. The kit comes complete with mounting hardware, adapters, and phenolic thermal spacers to minimize heat transfer between the cylinder head and fuel system.

This conversion kit allows you to run high-performance top-feed injectors—such as COBB 1050x or 1300x²—without replacing the Tumble Generator Valve (TGV) assemblies. Perfect for Subaru owners targeting increased horsepower or a Flex Fuel setup, it expands your fueling upgrade options beyond the limitations of side-feed injectors.
