This kit includes seals, o-rings, and clips for you to use with the Hyundai OE injector upgrade (35310-2GTA0).
You will need to source your own injectors by ordering 35310-2GTA0, and these components will give you everything you need for a plug and play installation.
The image is to give an idea and is not an actual photo of the parts since they are still in their sealed, factory packaging.
