Product is an OEM replacement. So far so good. Installed the part and it appears to be working as designed. My old control valve partially functioned, but when it was closed you could still feel a little exhaust gas escaping, which is probably what killed my air pump. Still waiting for the replacement air pump to arrive so I can see if my OBD codes clear after replacement of the two parts.
