I would have to go look that up and being as it's a Gen 3 generally don't do much looking up but that's the electric EGR valve sitting on the back of the head of this 2ZZ engine I didn't think Delphi made that part maybe they remanufacture that part I don't know to be honest this is another part I don't see how you could really screw up if you are a manufacturer of these type of parts like Delphi and the Toyota company of similar I just bought one of these for a generation 3 and installed it on another car a few weeks ago it was I think $159 and was the updated or the newer of the part I don't think there's any further updates but I don't know who all covers this part It's a pretty simple part it just has an airway and an electric motor and a ramp that opens up the valve where it needs to be It's kind of like the three-way coolant control valve but for the EGR and all metal You think about a part like this and you wonder how you could screw it up but buy a non Toyota part and you might get to find out very prematurely for $159 or whatever I paid I think I would stick with the Toyota part and it's not something you're going to be replacing very often more than likely you're going to replace this part and then the engine's going to blow and well that's another whole ball game this model is not rare.
