It might be difficult to find something worse than the OEM part.

Would anyone happen to know if there are any other manufacturers of the RCM other than AFL Stribel Production GmbH? I have not noticed any by looking at the stock photos that sellers are using. All stock photos I have seen of RCMs for sale either don't show the front (printed) side of the cover, or, if they do, the Stribel logo is always present. I'm guessing that Standard Motor Products, Airtex/Wells, BWD, etc. , are simply distributing the Stribel relay? If so, why not just buy the least expensive one you can find?
