You should have the black one everybody wants. They do go out so get a spare. And if you take it to the dealer don't let them change it cause they will on recall. It happen to me. I wanted the old part and they wouldn't give it back.

I didn't have that problem. I took mine in on the recall and it has been working for 2 years now no problems. I keep a spare JIK but they also gave me back my old one.

The Ford dealer in Kenai, Alaska told me they would replace my black CPS under their recall, but they were not willing to let me keep the black one as a spare. So I refused and told them no to replace it under the Ford recall.
OK... I've read everything. There was a question about heat way up the line and this is more relevent than most imagine. There are references to the thickness of plastic, and to the gap from the sensor to the gear. Here are some facts about hall-effect sensor magnets:
Heat: Magnets work until they get hot, then they stop working - permanently. Variations of heat causes variations of gaussian loss (fancy-schmancy word for magnetic strength loss). An inexpensive magnet that is pliable/flexible for the manufacturing process has a max temp of 212 degrees F, then it begins to lose it's magnetism. The "really good one with the strong magnetism" might have a rare-earth magnet, which is good up to 284 degrees F. The flexible one is easy to work with, but the rare-earth magnets are very brittle and a bugger to shape. Somebody has to manufacture the magnet to fit in the head and based on what I've read about CPSs, nobody has contacted the right vendor yet. I work with hall-effect sensors all day and I know who makes the good ones for the equipment I work with.
Time: Magnets weaken with time, heat near their limit, exposure to magnetic or strong electircal fields, and a few other factors we don't encounter in the truck.
Distance. distance! distance!! Magnets lose their pull exponentially with distance. Say you have a 1/16" gap and you move the magnet to a 1/8" gap - you just lost 75% of your magnetic pull. All of our hall-effect sensors at work have threads and double-nuts to precisely set the gap and adjust the gap for time/vibration. That one item right there puts us Ford owners on the defence.
The magnetic material in the CPS can deliver the goods or strand us in "the hood", but the gap! If the engineers designed the gap to be adjustable, we could dial and drive in many cases. As things are, the CPS is allegedly set right from the factory and we can shim it to open the gap - but we'd have to mill plastic off the shoulder of the device to close the gap. Re-designing the gear that the sensor faces would make a huge improvement.
So.... after reading all of this.... has anyone concluded on what the best CPS is that is still in production? And where I can get one??? Well I actually need a few, 4 to be specific.

The one you get from your local Ford dealer or riffraffdiesel.com. The part number will be DU-87.
