Installation Notes

  1. Disconnect the battery and relieve the fuel system pressure according to your engine's service manual.
  2. Carefully disconnect the electrical connector and fuel line from the old injector.
  3. Remove any mounting hardware and extract the old injector from the fuel rail.
  4. Lightly lubricate the O-rings on the new injector with clean engine oil.
  5. Press the new injector firmly and evenly into the fuel rail until it is fully seated.
  6. Reinstall any mounting hardware and tighten to the manufacturer's specification.
  7. Reconnect the fuel line and electrical connector, ensuring they click securely into place.
  8. Turn the ignition key to the ON position (without starting the engine) for a few seconds to prime the fuel system and check for leaks.
  9. Once confirmed there are no leaks, start the engine and check for smooth operation.

Troubleshooting & FAQ

How do I know if my fuel injector is failing?

Common signs of a faulty fuel injector include rough idling, engine misfires (often with a corresponding trouble code), poor acceleration, increased fuel consumption, or a noticeable smell of gasoline.

Is this a direct fit for my Suzuki DF20ATHL?

Yes, this injector is confirmed to fit the Suzuki DF20ATHL for model years 2014–2015. Always cross-reference your exact model and year with our compatibility table to ensure a perfect match.

What is the difference between Suzuki part 15710-89L00 and 15710-50M00?

The part number 15710-50M00 is the official supersession for 15710-89L00, meaning it is the newer, updated version from the manufacturer. They are functionally identical and fully interchangeable.

Do these injectors require programming or calibration?

No. These injectors are pre-calibrated and 100% tested at the factory to match OEM specifications for fuel flow rate and resistance. They are designed for direct installation with no additional programming required.

Can I replace just one injector, or should I replace all of them?

While you can replace a single failed injector, it is often recommended to replace them as a set, especially on older engines. This ensures consistent performance, fuel flow, and spray patterns across all cylinders.

What is the main cause of fuel injector failure?

Fuel injectors most commonly fail due to clogging from fuel contaminants, sediment, or ethanol-related deposits. Electrical faults within the injector's coil can also occur over time.

OEM vs. Aftermarket?

This listing is an aftermarket replacement (not OEM). Built to OEM-level specifications with comparable materials. Manufactured in an ISO 9002 facility, batch-inspected for consistency.
