Review on Enhance Efficiency with Standard Motor Products RU-560 Blower Motor Resistor Assorted, One Size by Frank Mayes

Physically the same size and fits where it should. Previously only the medium and high speed bypass worked, now all four speeds work, but the highest speed seems a bit slower or less powerful, and the lowest speed barely bleeds air. I believe this is because the resistance values of this device were averaged to make it cross platform or model, or the wide tolerance window (to keep costs down) for the resistors, but they are 1/3 to 1/4 Prices. OEM works.
