Product review (2 stars): I installed it anyway and it works fine but the SAME third-party brand name could be bought ...
Bought this from  ASM Trading. Definitely an aftermarket product and NOT OEM, and product was without the insulator sleeve.  I installed it anyway and it works fine but the SAME third-party brand name could be bought by other merchants for less than 1/2 of the price I paid, thinking it would be OEM with the insulator sleeve on the wires like the original.
