What You Get

• Set of 4 rebuilt genuine OEM Hyundai/Kia fuel injectors

Vehicle Fitment

These injectors fit the select 2.4L applications below when the vehicle's original injector is 35310-25200 / L021.

Check the number before ordering: Hyundai and Kia used more than one injector across their 2.4L engines. Match 35310-25200 or L021 to your original injector, or confirm fitment by VIN. A matching year and engine size alone is not enough—especially for 2007 Sonata models.

How We Rebuild and Test These Injectors

A genuine OEM core is only worth reinstalling if it passes inspection and testing. Our process focuses on the things that matter most to how the engine runs: sealing, spray quality, and consistent fuel delivery across the set.

Questions About 35310-25200 Fitment

Are these genuine Hyundai/Kia injectors or aftermarket replacements?

They are rebuilt genuine OEM Hyundai/Kia injectors. We service and test factory injectors rather than selling replica replacements under this listing.

Will 35310-25200 fit any Hyundai or Kia with a 2.4L engine?

No. Engine size by itself does not identify the injector. Other Hyundai/Kia 2.4L applications use different part numbers, so confirm 35310-25200 / L021 against the original injector or the vehicle VIN.

Is 35310-25200 the same as 35310-2G300?

No—do not assume those numbers are interchangeable. Some later 2.4L configurations use 35310-2G300 or another injector. Order the number specified for your vehicle.

Why does my 2007 Sonata need an extra fitment check?

Injector applications can differ by production configuration during that model year. Matching your original injector number or checking the VIN is the safest way to confirm which version your Sonata uses.
