Cobb 08-21 Subaru STI Fuel Rails - 343150

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.

Why?

Upgrading your Subaru's fuel system is required in order to take advantage of airflow modifications such as intakes, exhausts, or turbochargers. The COBB Fuel Rail Kit allows for increased fuel capacity and consistent performance at each injector. Pair them with the COBB Fuel Line Kit and Fuel Pressure Regulator Kit to build a complete system.
