Oh and here's a
diagram where I put my sensors
A = ambient
B = Chargcooler coolant
C = After FMIC
D = After Chargcooler
I was a bit paranoid when I mounted the sensors, so I bought some ally hose joiners (about 4 mm thick),drilled a hole and then taped a thread inside. I then glued the sensors into anodised blue hose adapters (the type you find on expensive braided hoses for fuel and oil lines) which I could then screw into the ally hoses. It was a bit pricey, but atleast none of the sensor will fall off and fall into the airstream.
