A long answer would be to read this thread - http://www.thedieselstop.com/forums...blue-cam-position-sensor-perdels-test-257398/
The short answer is the black is still the best but unavailable. The dark blue comes in second, and the Ford recommended grey comes in a distant third. All of the non-international brands come in so far behind the pack it isn't worth considering. For example, some people have got the Echlin CPS to work by adding about a half pound of ferrite chokes to various wires. None of that is needed with the International CPS line.
