The Subaru Fuel System Package Includes: Fuel Rails, Fuel Rail Line Kit, Fuel Pressure Regulator for Fuel Rail Kit, Top Feed 1050x Fuel Injectors, and the AEM High Flow Fuel Pump.

Requires custom tuning.

The COBB 1050x Fuel Injectors provide increased fuel flow while maintaining stock idle and driveability with proper tuning. Corrosion resistant internals make them compatible with all known fuels, capable of extended service life with corrosive fuels. Replaceable inlet filter extends service life.

The COBB Subaru Fuel Pressure Regulator Kit is a plug-and-play solution that is simple to install. It requires no cutting of factory hoses and is multi-fuel compatible. This kit includes the fuel pressure regulator manifold reference relocation kit and is designed specifically to be used with COBB Fuel Rails and Lines.

The COBB Subaru Fuel Rails are constructed of 6061 Billet Aluminum and feature black anodizing with a laser etched COBB logo. Each rail comes with -8 AN to -6 AN adapters pre-installed to allow for plug and play installation with the COBB Fuel Line Kit. Included hardware and adapters allow these fuel rails to be installed using either stock style or Injector Dynamics Fuel Injectors. Phenolic thermal spacers and stand-offs provide a heat barrier between the cylinder head and fuel system and are included with each kit.

The COBB Subaru Fuel Rail Line Kit is designed to be used along with the COBB Fuel Rail Kit. All lines are pre-assembled with double-swivel sport crimp style hose ends and ready for installation. Stainless reinforced PTFE line with black covering has a 3" minimum bend radius which allows for a straight forward installation when used as intended. With a 2500psi operating pressure and >10000psi burst pressure, these lines are incredibly robust.
