Yes Breu was the OEM for my car 560SL. But when I bought the wires I had to replace the resistor shells on cylinders 3 and 4 because mine were angled. Also the wires did not come with the wire number markers or rubber sheathes that the wires pass through. In taking the wires appart I was un able to do it without twisting the wire right out of the theaded terminal connector so I had to purchase 2 terminal connectors so I could cut the wire and replace the two threaded connectors to screw on the resistors. After that I said the hell with installing the wire markers of rubber sheaths. If I had to do it again I would try the Bosch or see how the wires are delivered from the dealer. All told my wire set with two new angled resitors cost over $200.00

Moral

Just because you find the OEM manufacturer does not mean you get the same thing your car was delivered with.
