Detailed Product Information

Delphi EX631117 is a replacement fuel injector intended for direct fuel metering in the engine’s injection system. It is suited for drivers and technicians servicing Honda Civic and Toyota Corolla fuel system repairs where consistent injector operation is required. The included instruction sheet supports identification and handling during installation, and the injector is backed by Delphi’s OE-focused manufacturing knowledge.

Common Issues This Injector Can Address

• Hard starting caused by poor fuel atomization
• Rough idle from inconsistent injector output
• Misfire conditions related to fuel delivery imbalance
• Reduced engine performance from restricted or worn injector operation
• Fuel trim problems tied to injector wear or contamination

Installation Notes

Confirm the injector part number and vehicle application before installation. Clean the fuel rail and sealing surfaces, inspect O-rings and connectors, and follow the instruction sheet included in the package. After installation, verify fuel pressure, check for leaks, and clear diagnostic trouble codes if required.

Quality Assurance

Delphi builds aftermarket parts using OE experience and knowledge developed through service to major automakers. That background supports consistent fit and function expectations for fuel injector replacement service.
