Most knock sensors come from China. When it came time to replace mine, I searched for ones from the US/Japan and couldn't find another source. Even OEM Subaru couldn't confirm that the part didn't originate in China. I wound up w/Ebay $5 knock sensors and haven't had a problem. If you don't want Chinese junk, ask the vendor where the part was manufactured, don't expect a part for a Japanese or any other country's car to be made in that country; China is, at the moment, to be one of the cheapest places for manufacturing car parts
