I bought the hundai purge valve, I went to autozone and checked out the Dorman one, it is noticeably cheaper in quality, the part from the actual hundai dealer seemed better like a better quality, it had a different part number (28910-22040) than the Dorman (911-800) and was like 10$ more, I felt comfortable putting in the actual hundai part. No codes, but I haven't really pulled it out to check on it, it's been in there for about a year now.
