I talked to the dealer who sold me the wires. He assured me that they are 100% OEM. He even went throught the trouble of checking all the wires they have in stock to be reassured. Come to think of it, the wires that that I changed out of the MR2 were the exact same wires that I bought from him. Well, for future references, if anyone is unsure what the OEM wires look like for the second gen. MR2 Turbo, now we know for sure.
If anyone is looking for brand new OEM parts for their MR2, you should check into this dealers store on Ebay. He's got some hard to find replacement parts, and he ships quick.
