Would you explain both of those statements please Klaus.

Both the NTK and Bosch sensors use internal heaters to get to 900 degrees C, right? I would think that you'd want a spot in the exhaust stream that won't go over 900C at it's hottest, but I can't see the reason for choosing the coolest spot. Seems like that would be further downstream that necessary.
