I read here and on Facebook that the Crank Position Sensor is prone to failure.

Just wondering if I should purchase one from the States to keep just in case and before it fails as it's only $50 considering I have 122,000k or 75,000 miles on my clock and don't want to be without my car as these items are much more expensive in Oz and harder to get hold of quickly.

Here are two items I am looking at. If someone can confirm they are the right items it would be much appreciated.
