Impreza TOP FEED fuel rail kit - JDM (-08)
Our Fuel rails run in parallel and have a much higher rail capacity than OEM, anapproximately 35% increase in internal flow capacity (dependent on fuel pumps and feed lines to engine bay). Made from T6-6061 billet stock, fully CNC machined with a central fuel inlet. It is possible to run dual return lines or pressure sensors for motorsport applications and R&D requirements.

Fuel rails for high horsepower and demanding motorsport applications. Larger power requires more fuel. Stock rails are plumbed in series, and really don't have much reserve capacity. This means you run the risk of leaning out injector number 4 when you have big fuel requirements. This can cause costly engine failures. All of our kits come exclusively with Goodridge 910 Aramid hose with CNC Aluminum Double Swivel hose ends (no more hose kinks when installing and lining up two angled ends).
Laser cut and CNC bent bracket houses the fuel return lines and the OE regulator just underneath the intercooler (it will clear larger aftermarket top mount intercoolers). If aftermarket fuel pressure regulators are used, you will need to order the optional remote fitment kit as well. All components are available separately if required.
Please send the inquiry to technical support/customer service. These fuel rails are available exclusively in North America through Rally Sport Direct
