Subaru WRX Top-Feed Fuel Injector Sets

$474.32

Injector Set

Application and injector fitment

Supported Subaru WRX / STI top-feed applications.

Injector selection

Select the required injector family and flow rate from the product dropdown. Each choice must be calibrated using the data for that exact injector and the fuel pressure used in the vehicle.

Connector, length and O-ring check

Confirm model-year and injector arrangement before ordering. Connector and body-length requirements vary by injector family.

Use the Suggested fitment parts selector only where the chosen injector requires a wiring adaptor, connector, extension or spacer. Do not add hardware already included with a direct-fit application kit.

Installation and calibration

Professional installation is recommended. After changing injector flow rate, the ECU calibration must be updated for injector flow, dead time/latency, fuel pressure and fuel type.
