The part is not "like OEM", it is the Genuine OEM part sold by the vehicle manufacturer. Warranty Duration. Typically only ONE part from ONE of the callouts will be included. See the Compatibility table "Notes" section for details about the part you are buying.
I purchased this plug to repair the PDC wiring that was damage in a accident. The oem harness was not available anymore, so I decided to repair it. This worked great, and the best option for the money.
