Most I see for sale don't list the manufacturer. If you call GAP, they'll probably tell you who is supplying their current stock. They may even have a few to choose from if you're really concerned:
GAP: http://www.germanautoparts.com/Volks...f/Climate/82/2
PartsGeek has one cheaper, but I don't know "Nissens" from Nissan, so can't vouch for it's quality.
