Careful now. They are made in China now. Have been for some time. I don't know "WHEN" that occurred. Shortly before I left O'Reilly in 2019, they were beginning to stock Standard Ignition products, all of which are now outsourced to China. I never got a chance to verify that with the Blue Streak line, but I suspect it is the same. I try to look for older NOS parts on ebay. If the box isn't old and faded, I stay away. So far, it's worked well.
