Blue Streak 10037 9.0mm 8cyl Spark Plug Wire Set NOS Read Description. These are NOS open box. The tape around a couple of them is peeled back a little...if this affects the wires I am not sure. Please cross reference your vehicle to the part number to assure fitment. These were designed for older GM vehicles but i do not know the exact makes or models. Box is dusty from sitting on a shelf. These are from at least 2012. See photos for condition and description.
