Power Enterprise fuel injectors are known for quality and accuracy. There are no injectors trusted more in Subaru tuning than Power Enterprise injectors. These 850cc injectors are side-feed and suitable for the 04-06 STi, Legacy GT, and Forester XT. Power Enterprise 850cc injectors offer increased fuel flow and direct plug-and-play installation. These injectors fit right into the factory fuel rail and attach to the factory wiring harness using the provided clips. The PE 850cc injectors are capable of supporting over 450hp and have a .85ms solid injection time.
Larger injectors are usually required when performing a turbo upgrade, but can also be a beneficial upgrade alone with a fuel pump. Regardless, upgraded injectors will require ECU tuning. We also recommend upgrading to Agency Power or Perrin fuel rails and a Walbro 255lph fuel pump kit (sold separately) when using upgraded injectors. These injectors are special order. Please check availability with us before ordering if you are in a hurry. No cancellations or refunds are allowed on special order items.
