CF10780R

OBX Red Fuel Injection Rail for 04-06 Subaru STI (US Spec ONLY)

Fuel Injectors

CNC machined from billet 6061 T-6 Aluminum
Precise bolt-on fitment
Designed for quick and easy installation
Intended for both N/A and forced induction setups

OBX Fuel Injection Rails are designed to prevent injector pulse on lean conditions from lack of adequate fuel reserves behind each injector.

This unit is a side feed unit designed to work with the US Spec STi engine only. This unit will not fit the standard WRX engine. The bore on each rail is considerably larger than the OEM diameter allowing for a larger fuel reservoir. This unit is a perfect upgrade for those who have installed a larger turbo and injectors.

Note that no fuel lines are included and will need to be sourced out according to your particular fuel management setup.
