FAQs
How do I know if this injector fits my vehicle?
Compare the OEM reference number on your current fuel injector with the CI XPSI57 specifications provided in your vehicle service manual.
Should I replace all injectors at once?
Yes, it is highly recommended to replace all injectors in the fuel rail simultaneously to ensure uniform fuel delivery across all cylinders.
Does this injector come with O-rings?
Please inspect the product packaging; if they are not included, always purchase new O-rings to prevent potential fuel leaks.
Is special equipment needed for installation?
Standard mechanic tools are typically sufficient, though a fuel pressure gauge is recommended to safely depressurize the fuel system before starting.
What is the primary sign that an injector needs replacing?
Common symptoms include rough idling, reduced fuel economy, engine misfires (P0300-P0304 codes), or a sluggish throttle response.
Troubleshooting
Engine still misfiring after installation
Verify the electrical connector is fully seated and clicked into place, and check the wiring harness for any signs of corrosion.
Fuel leak at the injector base
Ensure the O-ring was not pinched during installation and is properly seated in the intake manifold port.
Rough idle persists
Check that all fuel injectors in the bank are matched and that the ECU does not require a 'learned value' reset after the component replacement.

Setup, Compatibility & Care
Before installation, ensure the engine is completely cool and the fuel system pressure has been safely relieved according to your vehicle's service manual. Carefully disconnect the 2-pin rectangular connector and remove the fuel rail to access the injectors. Ensure the new O-rings are lightly lubricated with clean engine oil before seating the injector into the fuel rail and intake manifold. Always verify the OEM part number on your existing unit matches the XPSI57 specifications. To maintain injector health, use a high-quality fuel system cleaner periodically to prevent the buildup of deposits that can obstruct the fuel spray pattern.
