How much does a used fuel injector cost?

Used fuel injectors typically cost between $25 and $85 per unit. High-pressure GDI (Gasoline Direct Injection) or Diesel injectors may be higher due to their complex internal solenoids.

Are the fuel injectors flow-tested?

Yes. Every used injector undergoes a pulse-test on our specialized bench. We verify that the flow rate (cc/min) and spray pattern meet original OEM factory specifications.

Do I need to replace the O-rings on a used injector?

While our injectors include the original seals, we strictly recommend installing a brand-new fuel injector seal kit (O-rings and spacers) to prevent vacuum leaks or fire hazards.

Will this injector match my part number?

Yes. We match your replacement unit by the stamped OEM part number. This is vital to ensure the correct electrical impedance (Ohms) and fuel delivery for your engine's ECU.

How do I know if my fuel injector is bad?

Common symptoms include engine misfires (P0300 codes), rough idling, poor fuel economy, or a strong smell of unburned gas from the exhaust.

Are used GDI injectors available?

Yes. we stock high-pressure Direct Injection units. These are ultrasonicly cleaned and verified for high-pressure seal integrity before being added to our inventory.

Do you check for electrical continuity?

Yes. We perform an Ohm-meter test on the internal solenoid. If the resistance is out of factory range, the injector is rejected to prevent damage to your vehicle's computer.

What causes a fuel injector to fail?

Failures are usually caused by carbon buildup on the nozzle, internal spring fatigue, or 'clogging' from debris that passes through a failing fuel filter.

Should I replace one injector or the whole set?

While you can replace just one, we recommend replacing injectors in sets or 'banks' to ensure even cylinder-to-cylinder fuel distribution and smoother engine performance.

Genuine OEM Fuel Injectors for All Engines

A clogged or leaking fuel injector ruins your engine's efficiency and can even lead to catalytic converter failure. At Falcon Car Parts, we specialize in providing genuine used fuel injectors that deliver precise fuel metering. Why settle for generic aftermarket injectors that cause rough idles?

Every used fuel injector we ship is salvaged from low-mileage donor vehicles. Our technicians verify the pintle movement and the seat seal, ensuring zero 'dripping' when the injector is closed, providing you with a reliable and efficient fuel system solution.

Flow Matched: Verified to deliver equal fuel volume per pulse.
Ultrasonicly Cleaned: Nozzle tips are cleared of carbon deposits.
VIN Specific: Accurate matching for GDI, Port, or Flex-Fuel units.

Our 6-Point Quality Check for Fuel Injectors

Combustion efficiency is our standard. Every used injector passes this inspection:

1. Solenoid Resistance Audit: We verify internal coil health with a digital Ohmmeter.
2. Static Flow Test: We measure total fuel delivery volume over a 30-second constant pulse.
3. Dynamic Spray Audit: We visually verify the spray atomization pattern under strobe lights.

4. Leak-Down Test: We ensure the injector remains 100% drip-free under full fuel rail pressure.
5. Ultrasonic Tip Cleaning: Every nozzle is cleared of microscopic carbon deposits.
6. Connector Pin Audit: Electrical pins are checked for bending or green oxidation.

Common Questions About Buying Used Fuel Injectors

Used injectors usually range from $25 to $85. Direct Injection (GDI) models are slightly higher due to their complex high-pressure seals and solenoids.

Absolutely. OEM used injectors are superior to many "remanufactured" aftermarket units because the internal parts remain factory-spec. We bench-test every unit for flow and spray quality.

Yes. We recommend installing new Viton O-rings during installation. Used O-rings can flatten or harden, leading to fuel leaks or vacuum issues.

Yes. We match your part based on the manufacturer's 10-digit or alpha-numeric code stamped on the injector body. This ensures correct fueling and ECU compatibility.

Cheap aftermarket injectors often have inconsistent flow rates, which can cause lean or rich misfires. OEM used injectors maintain factory-perfect calibration.

Yes. A 'stuck open' injector can flood a cylinder and cause hydrostatic lock or wash oil away from cylinder walls. A 'clogged' injector causes lean misfires that melt pistons over time.

Yes. We verify that the electrical plug housing is not cracked and that the pins are clean and free of corrosion.
