should all OEM NOS Inter cooler hoses have the part #'s stamped on them . I know Kirban's after market replacement hose's are made from the same manufacturer and don't have the part #'s on the hoses . but shouldn't Gm nos be stamped? . Thanks
If I remember correctly, I have new oem turbo and uppipe hoses in gm boxes that do not have any white marking or letters. Do not know why but they don't.
